PT-53

Gilson offers Constant Temperature Viscosity Baths for testing asphalt. Although designed for use with capillary viscometers, the baths have solid-state circuitry and are ideal for general laboratory work requiring precise temperature control. All use 12x12in (305x305mm), DxH Pyrex bath jars for easy visibility.

PT-53 Viscosity Bath has selectable temperature presets and a variable control to set temperature at any point within their ranges. Temperature can be adjusted precisely within hundredths of a degree. A stainless-steel encased thermistor in the baths senses temperature. Bath Covers have seven 2in (51mm) diameter holes for viscometers and two 3/8in (10mm) holes for ASTM thermometers. A white-coated stainless-steel baffle plate aids viewing of viscometers. Lighting is by fluorescent lamps. The circuitry is in base platform drawer on ball-bearing glides for easy access. Temperature range is 20°-100°C. Presets are approx./fine tune 10 fixed. Control is proportional ±0.01°C. Mixing features a motor-driven stirrer. Unit has several over-temperature protection standards, two heating elements and is 900 Watts. PT-53 also boasts a baffle background for viewing. Est. Ship Wt.: 52lb (24kg).

The PT-53 has three safety features: A second thermistor provides fault protection for over-temperature condition. If such occurs, bath is shut off until user resets limit circuit. Heater power is shut off if control thermistor is disconnected. Power is shut off if bath liquid falls below safe operating level. Optional PTA-70 Drawer fits under unit for storing viscometers and accessories.

PT-56 Economy Viscosity Bath offers accurate testing conforming to ASTM D 445 temperature stability requirements. Unit includes glass bath Jar, Cover fitted for up to seven viscometers and one thermometer and a stainless-steel 1,000 Watt heater/circulator. The LED digital PID temperature control sets and reads in °C or °F. The PTA-71 stainless-steel Cooling Coil and the PTA-72 Safety Liner recommended to protect from hot oil splashes are available. Temperature range is 20°-150°C. Presets are one user settable. Control is proportional ±0.02°C. Mixing features a 7 or 15L/minute flow. Unit has two over-temperature protection standards, one heating element and is 1,000 Watts. Est. Ship Wt.: 36lb (16kg).

PTA-61 Bath Oil is recommended for PT-53, and PT-56 when testing to 100°C (212°F). Use PTA-59 Silicone Fluid with PT-56 for higher temperature work to 150°C (300°F). Bath jars hold about 5gal (19L).

For all units, order viscometers and thermometers separately. See separate listing for Vacuum Manifold and Pressure Regulators.
