Description
The HI-991300 meter features two operation button and is simple to use. All operations and settings, including calibration buffers and temperature scale selections, are made through these two buttons. It has a waterproof and compact casing rated for IP67 conditions and a large tri-line display. The meter has automatic pH calibration at one or two points and a single conductivity calibration. Other user selectable features include different TDS factors from 0.45 to 1.00, and a range of temperature coefficients from 0.0 to 2.4% for better conductivity or TDS solution temperature compensation. The meter is supplied with a multi-parameter probe specifically designed for this meter. Each meter is supplied complete with: HI-12883 pH/EC/TDS probe with built-in temperature sensor, DIN connector and 1mm cable pH 4.01 & 7.01 buffer sachets HI-70031 1413 µS/cm and HI-70032 1382 ppm 1 sachet of each HI-700601 Electrode cleaning solution (2 sachets) 100ml beaker Alkaline batteries: 1.5V AAA x 3 Rugged carrying case Calibration certificate of meter Calibration certificate of probe Instruction manual Main features: Simultaneous, pH, EC/TDS and temperature measurements on a large three line LCD display Selectable temperature unit pH electrode condition display mV of pH measurement for electrode check Last calibration points pH and EC HI-12883 dedicated pH/EC/TDS/temperature probe Probe quick connect system Battery life indication and low battery detection Auto-off function Keystroke confirmation tone Waterproof casing IP67 About the HI-12883 probe The HI-12883 multi-parameter probe, incorporates a domed shaped pH bulb rated from 0-13 pH, a single junction Ag/Cl reference electrode with gelled electrolyte and a retractable cloth wick junction, a graphite EC/TDS cell, and a temperature sensor in one convenient, rugged polypropylene body. In addition, to ensure against interference from transient electrical noise to pH, a solid-state pre-amplifier is integrated into the probe. The probe is rated from 0 to 50°C. pH Range -2.00 to 16.00 pH* pH-mV ±825 mV (pH-mV) EC 0 to 3999µS/cm (displays µS for µS/cm) TDS 0 to 2000ppm Temperature Range -5.0 to 105.0°C pH Resolution 0.01 pH pH-mV Resolution 1 mV EC 1µS/cm TDS 1ppm (mg/L) Temperature Resolution 0.1°C pH Accuracy @20°C ±0.02 pH pH-mV >±1 mV EC/TDS ±2%F.S.
