Portable ION / pH / ORP/ Temperature Meter

Suntex TS-250 meter features microprocessor design with IP65 waterproof protection. The simultaneous display of main measurement and temperature value make it idea for making field record. The three points calibration design enable a wide range of calibrated measurement. The TS-250  applies data logger and RS-232 interface. The advanced data logger function can automatically save the measurement with time interval up to 500 sets, and it can direct transmit through RS-232 interface to a computer or a printer. Hence, it not only can be as field measuring but also as field recording without hand writing or manually pressing the save button. The TS-250 features ion selective method & direct reading of ppm unit.
