Construction & materials

Built to the original equipment drawing, the Pressure Gauge uses Steel304 Steel304 and follows the same inspection checkpoints as the reference sample. Tolerances that affect installation are held to the drawing rather than adjusted on the bench.

• Steel304 Steel304 construction for daily and workshop use.
• Surface treated to resist corrosion in road and workshop conditions.
• Dimensional check against the reference sample before packing.

Technical notes

Deep dive. Reading drift together with a dim backlight is the classic low-battery signature on this two-AAA design; replace both cells together. A small offset after mechanical shock is cleared with the one-key reset, which re-zeroes the oil-filled diffusion silicon core at atmospheric pressure. Sluggish response to known pressure steps usually means a partially blocked pressure port, common after exposure to dirty pneumatic circuits. Condensation on the LCD below freezing is cosmetic and clears indoors, but sustained operation outside the -20 C to +60 C window voids stability expectations. A unit that will not power on after long storage often has corroded AAA contacts rather than electronics damage.

Application context. Hand-tighten the threaded connection and finish with a wrench on the hex flats, never on the case, so the 304 stainless housing does not twist. Apply appropriate thread sealant and match the ordered port code: M20x1.5, G1/4, NPT1/4, or G1/2. Confirm media compatibility before installation; the datasheet covers gas, water, and oil compatible with 304 or 316L stainless steel plus Viton or Buna-N seals, not corrosive media. On pulsating pump lines, mount the gauge behind a damper or snubber. Choose the gauge (G) or absolute (A) code correctly: absolute units read against a vacuum reference and will not zero at atmosphere.

Field note. Annual verification against a reference gauge or calibrator is justified by the declared stability of better than 0.25 percent of full scale per year; the manufacturer positions the instrument for portable measurement, equipment matching, and calibration-equipment roles. Change the AAA batteries when the graphical battery indicator falls low, and remove cells for long storage to prevent leakage into the compartment. Keep threads and the sealing face clean and lightly protected while the gauge rotates between test points. Store between -20 C and +60 C. After liquid-media use, drain and dry the port to protect the stainless fitting from residue.

Technical background. Use the manufacturer selection code rather than brochures: range unit (K for kPa, B for bar, P for psi, M for MPa), accuracy grade (0.25 or 0.5 percent F.S.), and connection type (G1/4, M20x1.5, NPT1/4, G1/2). Decide gauge versus absolute form first, since it cannot be changed later. Against analog glycerin gauges, this digital class offers fine resolution, one-key unit switching, bar-graph display, and better shock tolerance from the oil-filled core, at the cost of battery dependence. Buyers needing data logging or remote readout should look to transmitter variants, because this battery model is a local display instrument.

Technical background. Verified documentation declares CE conformity to EU electrical safety standards for the instrument. Accuracy is expressed as a combined figure of linearity, repeatability, and hysteresis measured at 25 C, stated as plus/minus 0.25 or 0.5 percent of full scale, which is the figure to quote in procurement files. Stability is separately specified at better than 0.25 percent F.S. per year. The pressure-form codes (G for gauge, A for absolute) and the overload rating of 1.5 times full scale come directly from the LEFOO datasheet, giving purchasing teams verifiable specification lines instead of marketing claims.

Technical background. Documented roles are portable pressure checks, equipment matching, and calibration support, with HVAC, cleanroom, refrigeration, building automation, and water and wastewater listed as application fields. Typical buyers are HVAC and refrigeration service contractors who need a trustworthy pocket reference, plant maintenance engineers verifying installed transmitters, and OEM panel builders fitting a digital display into equipment. Distributors of instrumentation and compressed-air accessories stock it alongside analog gauges. Because it reads gas, water, and oil compatible with stainless steel, one instrument covers pneumatic, hydraulic, and process spot checks across a maintenance round.

Field note. Consumables here are modest but real: two AAA batteries power the instrument, the port gaskets and seal washers age with each fitting cycle, and the oil-filled sensing cell drifts slowly, with stability specified better than 0.25% F.S. per year. Same-cycle practice is straightforward: whenever you change the batteries, inspect the port seal and re-verify the zero reading against open atmosphere; replace the seals whenever the thread connection is moved to a different medium or starts to show any weep.

Field note. The housing is 304 stainless steel, yet the LCD and electronics deserve gentler handling: ship units in their fitted foam with a protective cap over the port, and keep them within the stated storage band of -20 to 60 degrees C. For long shelf periods, remove the batteries entirely so leakage cannot corrode the contacts, and avoid leaving gauges on dashboards or radiators. Because shutdown current is below 5 microamps, batteries rarely leak, but prevention still beats repair.

Deep dive. Preparation is mostly thread work. Confirm which connection your order carries – M20x1.5, G1/4, NPT1/4, or G1/2 – and keep the matching adapters and thread seal tape on the bench. Fit a wrench only on the hex flats, never on the case body, and verify the medium is compatible with 304 stainless and the listed seal materials before pressurizing the joint. Insert fresh AAA batteries, wake the display, and check the ambient zero point before connecting to any live line.

Technical background. The operating window runs from -20 to 60 degrees C. In winter, a gauge carried from a cold van onto a warm process line will read low until it stabilizes; let it acclimate rather than blaming the sensing cell. Cold also saps AAA battery output, and the backlight usually dims first as a warning. In summer, shield the instrument from radiant heat near boilers and compressors, since sustained temperatures above the band accelerate both battery drain and long-term sensor drift.

Field note. Ordering in volume means decoding the part number carefully: range, unit code (kPa, bar, psi, or MPa), accuracy class of plus or minus 0.25% or 0.5% F.S., and connection style are all order-code selectable, and mismatched codes are the most common batch error. Request the calibration certificates issued with the batch, sample-verify several gauges against a reference instrument, and record serial numbers so annual recalibration can group units by batch and track their drift history properly.

Field note. The range code spans -100 kPa vacuum through 60 MPa gauge, and gauge (G) versus absolute (A) versions are genuinely different instruments; ordering gauge-pressure units for an absolute-pressure application guarantees offset errors from the start. Unit-code mistakes – a psi-coded gauge delivered when kPa display was wanted – are annoying but partially recoverable through the one-key unit switch. The hard trap is media choice: corrosive fluids attack the 304 housing and seals this gauge was never built to withstand.

Application note. Pressure connections are M20x1.5, G1/4, NPT1/4, or G1/2; working temperature is -20 C to +60 C; gauge (G) and absolute (A) variants exist; the instrument carries CE certification.

Application note. Measurement range spans -100 kPa vacuum through 0 to 100 kPa up to 60 MPa gauge, with overload tolerance of 1.5 times full scale.

Workshop note. Accuracy is plus/minus 0.25 percent of full scale (a 0.5 percent grade is offered), with stability better than 0.25 percent F.S. per year; the accuracy figure combines linearity, repeatability, and hysteresis measured at 25 C.

Workshop note. Power comes from two AAA batteries, with working current under 2 mA and shutdown current under 5 uA.

Supply note. The sensing core is an oil-filled diffusion silicon cell feeding a 24-bit AD processing chip and industrial-grade MCU; the 304 stainless steel case and fitting suit gas, water, and oil non-corrosive to stainless steel, with Viton or Buna-N seals.
