WalkLAB TI9000 Microprocessor pH Meter Trans Instruments in Bangladesh
 
Ease of use
Automatically lock reading when a stable reading is established.
Feature can be disabled to allow continuous reading display.

Automatic shut-off
Meter automatically shuts off after 5 minutes after last key command. Feature can be disabled while reading in continuous read mode.

One-touch calibration
The meter’s one-touch auto-calibration procedure uses only one button to activate the mode.
The unit will prompt and confirm offset and slope point calibration.
