OxyGuard Handy ­ Alpha, Beta and Gamma

OxyGuard Handy is a portable dissolved oxygen meter. It measures both ppm (mg/l) and % saturation. The Handy Alpha measures oxygen only. The Handy Beta and Gamma also measures temperature. The Handy Gamma has salinity compensation. The instruments are operated using foil switches. Each unit is supplied with a detachable clip for easy attachment to a belt or clipboard. The display on the Beta and Gamma can be backlit. · · · · · · · · · · ·

Galvanic type probe with short response time ­ ready for immediate use and no need for polarization & stabilization time. Measuring range ­ 0-50.0 ppm, 0-600% Sat. Waterproof ­ submersible but will float if dropped in the water. Excellent probe stability ­ one daily calibration check is usually more than enough. Tough membrane ­ can be wiped clean with cloth or paper towel. Long life probe ­ does not need regular renovation, only change membrane when necessary. Probe can be stored dry. Easily exchanged membrane ­ no more fumbling and struggling to replace a membrane. Compact and light weight ­ with a detachable clip for use on a belt or clipboard.
