Inficom D-Tek CO2 leak detector.

Detector with  rechargeable battery, mains charger, spare filters and  carry case

Picture actual item.

Good working order Used equipment from our own refrigeration workshop ( we are f-gas engineers but will be closing our  refrigeration side at the end of the year). Sensor is relaceable but with 1000 hour life this  has had very little use and we would not anticipate this needs replacing in the near future

Manufacturers spec is best introduction:

Provides Consistent, Accurate Responses to Next Generation Refrigerant

As the first accurate, reliable, highly sensitive, cordless refrigerant leak detector, the original D-TEK revolutionized the field. Now we have built on that technology leadership with the D-TEK CO2, the only hand-held refrigerant leak detector designed especially to detect carbon dioxide, the next generation refrigerant.

The D-TEK CO2 uses an innovative infrared absorption sensing cell which is extremely selective to carbon dioxide, yet its circuitry allows the instrument to equalize to the CO2 present in the atmosphere, so there is minimal risk of false alarms. D-TEK CO2 maintains its sensitivity over time for consistent, accurate and reliable performance. Its specialized infrared sensor cell lasts for approximately 1,000 hours, so you buy fewer replacement parts.

Additional features include a charging status indicator, sensor failure indication, sensor test mode and rechargeable NiMH (nickel metal hydride) batteries.
