Industrial pH meter
One-touch calibration function Realizes gentle measurement by combination with lead-free ORP electrode
- Improved single-touch calibration for greater ease of use
- Calibration history display
- Extensive interfaces (2-channel transmission output, RS-485 compatible, 6-relay output)
- Control output (upper and lower limits ON/OFF and duty control in a shared time and a zone)
- New pH electrode lineup
