General

Model GH-202F is a fully compact and handy battery operated instrument with a built in high sample drawing fan and high sensitive semi-conductor gas sensor. The basic versions are designed to detect and trace leaking sources of Flon 12, Methyl Bromide, Ammonia and Hydrocarbons. The GH-202F has an easy to read LED level meter and a audio alarm. The instrument incorporates a unique automatic balance and purge circuit. This allows the GH-202F to compensate for any background noise and temperature variations. A high and low sensitivity switch allows you to choose between a higher or lower range. When the battery voltage is dropped to replacement level, the power lamp starts flashing at the “ON” position.
