Product description
1. Characteristics:
Standard 483mm width 4U height 19 inch cabinet standard chassis, suitable for complete sets of equipment, can also be used in the laboratory.
Anti-acid, anti-corrosion sensor, anti-cross interference, advanced digital processing technology.
Service life: more than 5 years.
Linear expression of measurement signal output.
Output of multiple state signals: sound, light, picture, relay, communication information.
Digital temperature compensation.
Full Chinese menu operation (English version of order instructions).
.
Second, the field of application:
JNYQ-D- 21 analytical instrument can be used in the fields of air separation, chemical fertilizer, chemical industry, medical treatment, scientific research and so on.
.
Third, the principle of detection:
