3-in-1 pH ORP & Temperature Meter with Replaceable pH & ORP Electrodes and Temperature Probe ********           This 3-in1 is precision meter thatprovides precise pH, Redox Potential (ORP) and Temperaturemeasurements even under harsh conditions. Featuringreplaceable pH & ORP electrodes (uses standard BNC connector)and stainless temperature probe. Calibration can be 2-point calibration (range pH4 & pH7/pH10) or Single point.  It also has a built-in Automatic Temperature Compensation (ATC),measurements are automatically compensated for variationsin temperature. It is ideal for education and for measurementsin the field, pisciculture or fish farming and hatchery,food processing, floristics and orchids breeding, pools,schools & laboratories, analysis of fluids (ph-value)and other liquids, koi breeding, boilers, hemp breeding,water conditioning, cooling towers, industrial waste waterand other various industrial application. Special Features pH range of 0~14 with resolution &accuracy of 0.03pH Approximately 50 hours battery life (9V battery) Replaceable pH & ORP electrodes Replaceable Temperature probe Built-in ATC, adjust measurementsautomatically to the current temperature High accuracy (the most accurate and reliable pH/ORP/Temperaturemeter in the market) Precise with quick measuredreading results 2 point calibration (pH4 & pH7/pH10) for neutralbuffer solution Durable & reliable, long and trouble-free operation Specifications Range Accuracy Resolution 0 ~ 14.00pH ±0.01pH 0.01pH 0 ~ ±1999mV ±0.1% F·S ±1digit 1mV 0 ~ 100°C ±0.4°C 0.1°C Display: 4-digit LCD Power Supply: 9V Battery (up to 50hours) Operating Condition: Room Temperature: 0~50°C Humidity: =95%RH Input resistance: 10¹²O Size: 180 x 83 x 46mm Weight: approx. 290g (main unit)  Calibrations (at 25°C): Single point in neutralbuffer solution Double point in neutralbuffer solution plus an acid or alkaline buffersolution Offset regulation range: ±1pH Slope: 85 - 105% Automatic Temperature Compensation  (fixed at 20°C when probe is off, but it can bemodified or adjusted via calibration screw) Standard Set Includes 1 x pH ORP and Temperature (3-in1)Meter 1 x Mini calibration screwdriver 1 x Replaceable Temperature Probe 1 x Replaceable (BNC Type) pH Electrode 1 x Replaceable (BNC Type) ORP Electrode 1 x Protective black carrying case Quick Start Guide Standard packaging box ****************RegisteredAir Mail: US $19.00 (includinginsurance)     Copyright© 2008.
