Description
The YSI pH1200 operation is easy-to-use and includes a large, easy-to-read LCD. An autolock feature will hold the readings on the display once they reach stabilization. Simple 1-, 2- or 3-point calibration routine with automatic buffer recognition of US and NIST buffers and sensor efficiency function helps ensure the most accurate data. The instrument can be powered by batteries or through AC power.
Measure pH accurately in the laboratory with the YSI pH1200.
