RKI is pleased to announce the availability of a Phosphine (PH3) sensor for the GX-3R Pro. It is in stock and is the latest toxic gas option added to the line of GX-3R Pro sensors.

PH3 is a colorless, flammable, and explosive gas at ambient temperature that has the odor of garlic or decaying fish. Phosphine is used in semiconductor and plastics industries, in the production of flame retardant, and as a pesticide in stored grain.

The GX-3R Pro's PH3 sensor has a range of 0 - 20.00 ppm, and with a resolution of 0.01 ppm.

There are two ways to order a GX-3R Pro with PH3. One is to order the instrument new and configured with the PH3 sensor. See the price list link below for part numbers and configurations. The second way is to add the sensor to an existing GX-3R Pro.
