DW-1 pen-oxidation-reduction potential (ORP) Total Operating Instructions: * Remove the electrode protective cover, press the POWER button (red), potentiometer LCD should display; * The first part of the potentiometer electrode immersed in the solution acidity, attention Do not touch the bottom of the beaker solution; * slow agitation to the electrode readings stable, read the value; * testing is completed, clean the electrodes with water to remove contamination; dry with filter paper, the next sample can be detected; * When not in industrial pH meter, press POWER button to shut down the acidity of factory outlets, and put the electrode protective sleeve. * Automatic shutdown after laboratory pH meter, boot basis having secondary POWER button; Note: * To ensure measurement accuracy, after one week, with a cotton ball to wipe or rinse solution platinum foil; * found potentiometer LCD the need to replace the battery when the display brightness dims; Technical Specifications: * Measuring range: ± 999mV * Resolution: 1mV * Accuracy: ± 10mV (20 ℃) ??* Ambient temperature: 0 ~ 45 ℃ * Power: 2 × 3V button battery continuous Working time:> 150 (h) * Auto shutdown time: 10min * Dimensions: 147 × 28 × 15 (mm) * Weight: 0.05kg sension + PH1 portable PH meter Products: sensION + PH1 Series pH meter. Measure pH, ORP (ie, redox potential, sold separately ORP electrode) and temperature, simple operation, the instrument has automatically identify the function of standard buffer solution, the correction process is simple and fast technical parameters: pH measurement mode mode mode millivolt temperature mode range -2.00 ~ 19.99 -2000 ~ 2000mV -10.0 ~ 110 ℃ can also use oF selectable display resolution: 0.001 / 0.01 / 0.1 0.1mV 0.1 ℃ accuracy or slope slope: 58 ± 3mV / 10 pH units (sensION1) 48 -65mV / 10 pH units (sensION3) Accuracy: 0.2mV or reading ± 0.1%, both greater accuracy: 0 ~ 70 ℃ when ± 0.3 ℃; at 70 ~ 110 ℃ of ± 1.0 ℃ Display: The liquid crystal display (LCD) calibration methods: one, two or three-point calibration (pH values ??of 4.01, 6.86 or 7.00 and 10.01 buffer) Input: a BNC connector; with 5-pin connector hash pH / temperature or hash temperature electrode Package: waterproof, chemical resistant, dustproof Yantai acidity, 星枫 instrument acidity, industrial pH meter is provided by 星枫 instruments.
