Product Description

The Robinair No. 22791 uses infrared optics to create a refrigerant
leak detector that combines sensitivity, speed, battery life, portability,
and ease of use. This unit detects leaks as small as 0.15 oz/year,
and meets SAE J1627, J2791, and J2913 standards.

No. 22791 comes with a wall charger and a car charger for its
compact lithium-ion battery—which can power the leak detector
for up to eight hours of continuous operation before needing to
recharge. A choice of three sensitivity settings keep false alarms
to a minimum while allowing detection of even the smallest leak
in a refrigerant contaminated environment. A 30-second, self­calibration test occurs whenever the unit is powered on to ensure

optimal performance. A built-in replaceable lter blocks moisture

and particulates, preventing damage to the sensor.
