Detailed Description for Oxyguard Handy Gamma

The OxyGuard Handy is a portable dissolved oxygen meter available in 3 different models - the Alpha, Beta and Gamma. The Handy measures both ppm (mg/l) and % Saturation. The Handy Alpha measures oxygen only. Both the Handy Beta and Gamma measure temperature in addition. The Handy Gamma has salinity compensation. The instruments are operated using foil switches. Each Handy is supplied with a detachable clip for easy attachment to a belt or clipboard. The display on the Beta and Gamma can be back-lit for use in low light conditions. Features and Benefits: Galvanic type probe with short response time - always ready for immediate use without the need for polarization & stabilization time. Measuring range - 0-50.0 ppm, 0-600% Sat. Waterproof - submersible and will float if dropped in the water. Excellent probe stability - one daily calibration check is sufficient. Tough membrane - can be wiped clean with cloth or paper towel. Long life probe - can be stored dry, does not need regular renovation, only change membrane when necessary. Easily exchanged membrane - no more fumbling and struggling. Compact and convenient - has a detachable clip for use on a belt or clipboard. Display can be illuminated (back-lit). Reliable power source - standard 9 volt battery with more than 1000 operating hours and a low battery indicator. Comes with accessories as standard - Belt clip, Service kit including a spare membrane cap, membranes, electrolyte and tool. Specification: Handy Alpha ppm (mg/l) and % Saturation. Handy Beta ppm (mg/l), % Saturation and temperature. Handy Gamma ppm (mg/l), % Saturation and temperature. salinity compensation via foil switches. Probe type Galvanic cell, self polarizing, self temperature compensating. Cable length Standard 3 m. (10 ft.). Any length available on request. Operating conditions 0-50°C (32-122°F) Range Standard: 0-50.0 ppm (mg/l) and 0-600% Saturation, will indicate up to 199.9 ppm (mg/l) and 1999% Saturation. Accuracy Depends on calibration method, typically better than ±1% of measured value 1 digit when calibration temperature equals measuring temp. 10° C (18°F). Repeatability Typically better than ±0.5% of measured value. Response time 90% of end value in less than 10 seconds. Min. water velocity 3 to 5 cm/sec. (1 to 2 inch/sec). Accuracy, temperature ±0.2° C (Beta and Gamma). Salinity compensation 0-50 ppt salinity. Set using push buttons (Gamma only). Dimensions 96 mm diameter x 36 mm (3-3/4" dia x 1-1/2") + belt clip (if used). Standard accessories Belt clip, carrying pouch and service kit comprising spare membrane cap, membranes, electrolyte.
