Description
Key Features
- Double-row nixie tube: To display μg/L, pNa/mV and temperature simultaneously.
- Computer-based: To adopt high-performance CPU chip, high-precision AD conversion technology and 8usMTtechnology to complete multi-parameter measurement and temperature compensation with high precision and good repeatability
- High reliability: Single board structure, touch button, no switch knob
- Input impedance :> 1012Ω
- High sensitivity: In the static water sample, it can detect 0.2ppb (8pNa)
- Lasting stability: There is a very stable reading.
- Waterproof and anti-erosion design
- Network function: RS232 bi-directional communication, equipped with a printer or TLab8.0
communications and data processing software.
