Spesifikasi

Specification

Conforms to the specifications of: 

ASTM D942; IP 142; DIN 51808; FTM 791-3453

Oxidation Bath: Capacity: four (4) oxidation pressure vessels

Temperature Range: ambient to 275°F (135°C)

Bath Medium: 12.5 gal (47.3L) white technical oil

Features

  • Conforms to ASTM D942 and related specifications
  • Four sample testing capability
  • Available Oxidata® Pressure Measurement System

Test Method

The sample is oxidized in a pressure vessel initially charged with oxygen at 110psi (758kPa) and maintained at elevated temperature for a specified aging period. The pressure drop inside the pressure vessel is measured by means of a gauge or transducer.

Description

Oxidation Bath–Constant temperature oil bath holds pressure vessels at the proper depth for determining oxidation stability of lubricating greases. Microprocessor PID control provides quick temperature stabilization without overshoot and the unit is protected by an overtemperature control circuit that interrupts power should bath 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. Heavily insulated welded stainless steel bath interior has a pressure vessel support rack and overflow standpipe/drain to maintain proper working depth. Steel exterior has a corrosion-resistant polyurethane enamel finish.
