The PH400F is a laboratory benchtop pH meter that resolves to 0.001 pH with ±0.002 pH accuracy. It calibrates on up to five points. In addition, it recognises NIST, DIN, GB, USA and Merck buffer groups automatically. After every calibration it reports electrode slope and offset. As a result, you catch a tired electrode before it costs a result.
You can read in fast, medium or slow auto-read, timed or continuous mode. Moreover, the meter stores 500 GLP-compliant results with date and time. Finally, it exports them over USB or RS-232 to a PC or printer.

The benchtop pH meter serves municipal and industrial water laboratories, coagulant and chemical QC, and ISO 17025 and Blue Drop compliance testing. In addition, it suits food and beverage process control and teaching and research laboratories.
Hadron Group has supplied water-treatment chemicals, dosing equipment and analytical instruments from Pretoria since 1999. Our team uses these meters on site every week, for example for jar tests and plant surveys. As a result, we can advise on the right electrode, calibration standards and maintenance routine for your water. In addition, we support the meters across South Africa and the SADC region, with matching buffers, standards and probes.
Every stored result carries the date, time, calibration data and electrode condition. In addition, the log exports unchanged. In other words, it gives the traceability an accredited laboratory needs.
Stock pH 4.01, 7.00 and 10.01 for routine work. The meter recognises NIST, DIN, GB, USA and Merck buffer sets automatically. Moreover, we supply all of them.
