First, the use of instruments
1. "ZD - 2 type automatic potentiometric titration" my old factory products the modified product of the system, in the use and operation, with considerable coherence, in order to facilitate the operation and application of many old user.
2 "ZD - 2" when used separately as a pH meter or a meter (these two measurement items use the same scale). Suitable for:
Supporting the use of 3 ZD2 type and DZ1 type，
Suitable for:
(a) with different reference electrodes and reference electrodes, the capacity of the chemical laboratory was analyzed;
(two) constant control of a certain pH value, pNa value, or electrode potential;
(three) using a manual method for potentiometric titration to obtain such as a point or capacity analysis.
4. To enable the operator in the whole titration, reaction process, can accurately grasp the indicating electrode potential jump change, so the ZD - 2 type indicator, still using the easy to distinguish a variable transmission speed pointer type electric meter.
5.ZD - 0 with 2 ~ 10mV signal output function, the use of this function can be easily drawn out the entire titration curves, for the user to analyze and save. Requirements for recorder.
(one) the recorder must be at the center of zero (zero phase and instrument pointer should be consistent).
(two) input sensitivity: 0 ~ 10mV full scale。
Two, the technical performance of the instrument
1. Using alone: project scope measurement meter minimum sub grid electrode resistance precision PH:0 ~ 14ph + 0.1pH PNa:Na+2.3~2300 mg / liter measured potential 0~1400mV potential measuring ~ - 1400mV
2 temperature compensation method and range (pH and pNa are the same):
(one) manual compensation
(two) 5 to 60 C 3 end of the adjustment range: pH1 ~ 13 or + 100 ~ 1300mV.
3 titration pre control range: from the end of 1 ~ 3PH or 100 ~ 300mV。
Three, the working conditions of the instrument
1 indoor temperature: 0 ~ 35
2 air relative humidity: less than 85%
3 power supply voltage and frequency requirements: AC 220V + 10%, 50 + 4Hz.
