Water hardness tester water hardness tester water hardness meter quality testing refers to the total concentration of calcium and magnesium in water samples, it is an important indicator of water quality. The instrument uses the electrode test, by a large number of experiments show that it has the same accuracy and ED TA titration method, and avoid many shortcomings ED TA titration, such as operational problems, determine the end point of uncertainty, and is not suitable Use the color and turbidity of water samples. I. Introduction This instrument is built-in microprocessor chip, good looks, easy to use, and through the ISO 9001: 2000 and CE certification, has the following salient features: 1, using 601-S type water hardness combination electrode, which consists of measuring electrode, Ag / Ag Cl reference electrode and temperature combination electrode made of PVC sensitive membrane electrode measurements to novel neutral carrier for the active substance, calcium and magnesium ions in water samples selectively equal, having a novel structure, potential stability , fast response, easy to use features. 2, the electronic unit adopts intelligent chip design, with automatic calibration, automatic temperature compensation, data storage and other intelligent features. 3, self-select one of five units of water hardness: mmol / L, mg / L (Ca CO 3), mg / L (Ca O), mmol / L (Boiler) and mg / L (Ca), the other three units of H (French degrees), od H (German degrees) and oe H (United Kingdom) and can choose to use the W H-Link communications software. 4. Preparation of B 1, B 2 and B 3 three kinds of calibration solution. The instrument is suitable for industrial boiler water, universities, research institutes and industrial and mining field use, for high-precision measuring water hardness. 2, the instrument technical parameters: 2.1 Measuring range:. (A) water hardness values: 0 ~ 10 mmol / L is equivalent to other units: 0 ~ 1000 mg / L (Ca CO 3) 0 ~ 561 mg / L (Ca O ) 0 ~ 20 mmol / L (Boiler) 0 ~ 401 mg / L (Ca) 0 ~ 100 of H (French degrees) 0 ~ 56 od H (German degrees) 0 ~ 70 oe H (British degrees) Note: oe H , od H, of H can only choose (b) the temperature value in W H-Link communications software: 0 ~ 60.0 ℃ Note: The temperature unit is ℃ and ℉, can set your own. 2.2 Resolution:. (A) water hardness: 0.01 and 0.1 water hardness units (b) Temperature: 0.1 ℃ 2.3 Accuracy:. (A) water hardness: ≤ ± 5% FS (b) Temperature: ≤ ± 0.5 ℃ 2.4 Automatic temperature compensation range: 5 ~ 50 ℃ 2.5 measurements storage capacity: 99 2.6 in each store content: measured value number, measurement value, measurement unit, temperature, AT C or MT C status, date of measurement The measurement time and the calibration mode. 2.7 Calibration solutions: B 1 calibration solution - 2.00 × 10-2 mmol / LB 2 calibration solution - 2.00 × 10-1 mmol / LB 3 calibration solution - 2.00 mmol / L Note:. B 3 calibration solution is also used as an electrode immersed activated 2.8 calibration solution used way: The instrument uses two-point calibration, and there are two correction methods for selection: B 1, B 2 correction or B 2, B 3 calibration. (A) B 1, B 2 correction - using B 1 and B 2 calibration solution calibration calibration solutions for <2.00 × 10-2 mmol low concentration of water quality / L, such as boiler water. (B) B 2, B 3 calibration - calibration solution using B 2 and B 3 calibration solutions correction for general water quality. 2.9 waterproof design (waterproof grade IP 57) 2.10 Packaging: Instrument: (65 × 120 × 31) mm / 180 g suitcase: (360 × 270 × 76) mm / 1.7 kg 2.11 Power supply:. AA battery 2 Section (1.5 V × 2) 2.12 environmental operating conditions of the instrument (a) ambient temperature:. 5 ~ 35 ℃ (b) Relative humidity: ≤ 85%
