P615 PH/DO Meter
Features:
1. Large LCD screen with controllable white backlight
2. Built-in microprocessor chip has intelligent functions such as automatic calibration, ATC, data storage, function setting, auto-diagnosis, auto power off, and undervoltage prompt, etc.
3. Automatic recognition of 13 buffers with 3 kinds of options: Europe & USA, NIST and China.
4. Can set up pH measurement modes of high purity water and ammonia added pure water
5. DO mode has functions of ATC, auto salinity compensation and manual pressure compensation
6. New structure polarographic DO electrode can measure temperature, salinity and dissolved oxygen simultaneously, equipped with special DO electrode calibration sleeve, only need 3-5 minutes for polarization
7. Combined diaphragm cap make it extremely convenient to replace the sensitive membrane just by screwing the new cap to the electrode
8. Grade IP57 and equipped with suitcase for outdoor purpose.
