Many organisms are not equipped for high tolerances in shifts in temperature and salinity for long durations without fatal consequences. 8371 multifunction tool incorporates digital tests for temperature (ºC/°F) and salinity (ppt) displayed simultaneously on screen, commonly used by aquarists to measure the salt content in liquid without the need for conversions. The sensors provide excellent chemical compatibility, durability, reliability and efficiency. Additional features includes HOLD function, auto shutoff, and low-battery indicator, multipoint calibration, built-in NaCl, conductivity to TDS conversion factor, built-in NaCl temperature coefficient, selectable °C & °F, free batteries that work continuously up to 80 hours, water proof membrane keypad, low cost design with very high accuracy, quick response, easy to calibrate and built-in ATC to ensure 100% accuracy. Having an ATC in a meter is very important because even the slightest change in temperature affects the accuracy of reading results, ATC lets the meter automatically adjust to the current environment temperature. With CE Approval, this device has been factory tested to provide trouble-free performance and contains certified components to ensure safe, reliable and accurate results. Also, 8371 is waterproof & dustproof. This meter is protected from water projected in jets against the meter from any direction shall have no harmful effects as well as dust can not penetrate in a quantity to interfere with satisfactory operation of the apparatus or to impair safety. Key Features: Offers unquestionable performance, cost-effective and reliable! IP65 Waterproof housing (waterproof & dustproof) (Water splashed from any direction onto the housing have no harmful effects) CE Approved This device has been factory tested to provide trouble-free performance and contains certified components to ensure safe, reliable and accurate results. Dual display with ATC, simultaneous display of Temperature & Salinity °C/°F unit switchable Water proof membrane keypad Built-in NaCl Temperature coefficient Built-in NaCl Conductivity to TDS conversion factor Data hold, hold current reading freeze readings Low cost design with high accuracy Multi-point calibration Automatic Temperature Compensation Easy to calibrate with one touch only for calibration Auto Power-Off Function with non-sleep mode disable feature Low battery indicator Easy battery replacement, uses only 4pcs LR44 batteries Quick response and simple to use, all push-button operation Handheld, Pen size, Lightweight Design, easy to fit in pocket Allow resetting to factory default setting Calibration data for ranges can be retained & can be viewed anytime With over & below the limit value indicator Totally Brand New Specifications: Hold function to freeze current values Salinity range : 1.0~70.0 ppt (NaCl) Accuracy: 1% Full Scale + 1 digit Resolution: 0.1ppt Normalization Temperature: Fixed at 25°C Waterproof rating: IP65 Temperature compensation: 0~50°C Temperature coefficient: Built-in NaCl Temperature coefficient Operating temperature: 0~50°C Power requirements: 4 x 1.5V batteries (Type A76 or LR44) Power requirements: (last up to 80hrs continuous work) Auto power off : 20 minutes after last key op.
