E+H water analysis instruments are renowned for their high precision, stability, and intelligence, meeting diverse needs from laboratory to on-site online monitoring.
pH and ORP Measurement
pH Analyzer
E+H offers a variety of pH electrodes and transmitters suitable for harsh conditions such as high temperature, high pressure, and strong corrosion. Its Memosens digital technology simplifies calibration and maintenance and supports plug-and-play. Typical products include Orbisint CPS11D, Ceragel CPS71D, etc.
- Measuring range: 0-14 pH
- Accuracy: ±0.01 pH
- Process temperature: -15~135°C
- Process pressure: max 16 bar
ORP Analyzer
ORP (oxidation-reduction potential) measurement is used to monitor disinfection effectiveness and chemical reaction processes. E+H's ORP electrodes use the same platform as pH electrodes and can be quickly integrated.
- Measuring range: -1500~+1500 mV
- Response time: <10 seconds
- Applications: drinking water disinfection, swimming pool water, industrial wastewater
Conductivity Measurement
E+H conductivity meters are divided into contact and inductive types, covering ultrapure water to high-concentration acid and alkali solutions. Its Smartec series transmitters support multiple communication protocols.
| Model | Measuring Range | Accuracy | Application |
|---|---|---|---|
| CLS15 | 0.04~20 µS/cm | ±1% | Ultrapure water |
| CLS21 | 10 µS/cm~20 mS/cm | ±0.5% | Drinking water |
| CLS50 | 0.1~2000 mS/cm | ±0.5% | Chemical processes |
Dissolved Oxygen Measurement
E+H offers both optical and electrochemical dissolved oxygen measurement technologies. The optical method (Oxymax COS61D) requires no electrolyte and has low maintenance; the electrochemical method (Oxymax COS22D) has fast response and is suitable for low-concentration measurement.
- Measuring range: 0~20 mg/L (extendable to 200% saturation)
- Accuracy: ±0.1 mg/L
- Process temperature: -5~80°C
Residual Chlorine Measurement
Residual chlorine is a key indicator for drinking water and swimming pool water disinfection. E+H uses amperometric or colorimetric methods to provide continuous online monitoring. Typical product: Chloromax CCS142D.
- Measuring range: 0~5 mg/L (extendable)
- Accuracy: ±2% or ±0.01 mg/L
- pH compensation: built-in
Turbidity Measurement
E+H turbidity meters use the 90° scattered light principle and comply with ISO 7027 standards. Suitable for drinking water, wastewater, and industrial processes.
- Measuring range: 0~4000 NTU
- Accuracy: ±2% or ±0.01 NTU
- Light source: LED infrared light
COD, Ammonia Nitrogen, TP, TN Measurement
COD Analyzer
E+H uses UV absorption method or potassium dichromate method to provide online COD monitoring. Typical product: CA80COD.
- Measuring range: 0~5000 mg/L
- Accuracy: ±5%
