Product details
Product Introduction:
DDS-11A Digital Conductivity MeterSuitable for measuring the conductivity of liquids in the laboratory. It can not only measure the conductivity of general liquids, but also meet the measurement of conductivity of high-purity water. The instrument adopts a 3 1/2 position liquid crystal display, with clear readings
Technical Specifications:
1. Measurement range: Conductivity 0-105 μ s/cm, equivalent to a resistivity of ∞ -10 Ω· cm, divided into four basic ranges and two additional ranges (see table)
2. Accuracy: not greater than ± 1% (full scale) ± 1 word
3. Stability: ± 0.1% ± 1 word/2 hours (after preheating for 1 hour)
4. Working conditions:
Environmental temperature: 0-40 ℃
Relative humidity: ≤ 85%
Power supply: This instrument uses a power converter x power input: AC220V ≤ 10% 50Hz ± 1Hz converter output DC 9V
