DRX3 is a refrigerant and combustible gas leak detector with ATEX Zone 2 certification and a heated diode sensor. It detects A3, A2L, A1, HFO, HCFC, CFC, HC refrigerants, and tracer gas (95% N₂ + 5% H₂). A sensitivity of 1 g/year (stationary) and replaceable lithium batteries ensure safe, precise work in hazardous-area environments. What it's used for Detecting refrigerant leaks in HVAC/R systems Safe work in explosive atmospheres (ATEX Zone 2 / Class I Div 2) Detecting combustible gases: natural gas, propane, butane, methane Measurement with tracer gas (95% N₂ + 5% H₂) Handling A3 (R-290, R-600a), A2L (R-32, R-454B, R-1234yf), and A1 refrigerants Key features ATEX Zone 2 certification — allows safe use in hazardous areas and with A3 refrigerants Heated diode sensor — sensitivity of 1 g/year stationary, 3 g/year moving; sensor is field-replaceable Detection of A3, A2L, A1 refrigerants and combustible gases — covers a wide range: HC, HFC, HCFC, CFC, HFO, H₂/N₂, and heating gases Replaceable RXA3 sensor — no need to replace the entire detector when the sensor wears out (service life ~300 h) LED + audible + LCD leak indication — illuminated probe tip, bar graph, digital readout, and audible alarm 2.4 GHz Job Link connectivity — live readings in the app, range up to 200 m 60-hour battery life — 4 × AA lithium iron disulfide cells (Energizer L91) with 10-minute auto shut-off Selected specifications Type Refrigerant and combustible gas leak detector Model Fieldpiece DRX3 Sensor Heated diode, replaceable RXA3 Sensor service life ~300 h Maximum sensitivity 1 g/year stationary; 3 g/year moving Refrigerants A3, A2L, A1; HC, HFC, HCFC, CFC, HFO, H₂/N₂ (tracer gas) Combustible gases Natural gas, propane, butane, methane ATEX certification Zone 2 (II 3 G Ex ic IIA T2 Gc); Class I Div 2 Ingress protection IP54 Battery 4 × AA lithium iron disulfide (Energizer L91) Battery life ~60 h Wireless range 2.4 GHz, up to 200 m (Job Link) Operating temperature −20 °C to +50 °C Weight 442 g with batteries In the box 1 × DRX3 leak detector 1 × RXA3 diode sensor 1 × Carrying case 4 × AA lithium iron disulfide batteries (ATEX)
