K56100 Cigre Bath, Oxidation Stability Apparatus
Constant temperature aluminum block type bath for oxidation stability tests in accordance with the Institute of Petroleum (IP) testing methods. Accommodates twelve sets of oxidation and absorption tubes. Insulated block bath operates efficiently at temperatures of up to 200°C (392°F). Microprocessor PID control provides quick temperature stabilization without overshoot, and the bath is protected by a an over-temperature control circuit that interrupts power should block temperature exceed a programmed cut-off point. Dual LED displays provide actual and setpoint temperature values in °C/°F format. Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Contact your Koehler representative for information. A bank of twelve flowmeters on a movable stand regulates oxygen flow at 1 ± 0.1L/h to each oil sample per IP specifications. Includes soap bubble flowmeter for checking oxygen flow rate.
