Brand Name : | Dor Yang |
Product description
Double-row nixie tubes display PH value/mV value and temperature respectively. |
Computer-based: It adopts high-performance CPU chip, high-precision AD conversion technology and SMT |
technology to complete the multi-parameter measurement, automatic temperature compensation and instrument |
self-checking, with high precision and good repeatability. |
Reliability: Single board structure, touch button, no switch knob |
25℃ Conversion: Nernst electrode slope temperature compensation, pure water and ultra-pure water with |
addition of ammonia converted at 25℃. |
Standard liquid temperature auto-conversion: It pre-stores the temperature curve of the standard liquid; in the |
calibration, it can convert pH value of the standard liquid automatically at the set temperature. |
Auto-determination of error calibration: If the user wrongly uses the standard buffer solution in the calibration, |
the instrument will prompt automatically. |
