The Pro20i’s non-detachable cable provides temperature measurements (no temperature probe needed). The Pro20i stores 50 data sets and features One Touch Cal for simple DO calibrations within 3 seconds. Additional features include a backlit graphic display, a glow-in-the-dark keypad, and a tough, IP-67, impact-resistant waterproof housing. Includes meter, polarographic DO sensor, and built-in cable.
