The ZX-1 Heated Pentode™ refrigerant leak detector has a patent-pending microprocessor-controlled circuit, including constant battery and sensor condition detection. Features of the completely digital hand-held detector include: refrigerant-specific detection; detection of all halogenated refrigerants at levels below 0.1 oz/yr; tricolor visual leak size indication; flexible stainless probe; and tactile keypad controls with one-touch reset and adjustable sensitivity. A mechanical pump gives instant response and clearing, says the manufacturer. Nickel-cadmium rechargeable batteries and charger are included. The detector weighs about 16 oz (452 grams).
