LT-912
ULTRA PRECISE CONSTANT TEMPERATURE VISCOSITY BATH LT 910 0….+150°С ±0,01°С
Ultra precise cooling and heating bath LOIP LT 912 is designed for kinematic viscosity determinations with glass capillary viscometers at low temperatures, according to ASTM D445, ISO 3104, IP 71 and related specifications. Due to integrated powerful compressor refrigerating unit the instrument can achieve low temperatures down to -40°С within 1.5 hours. Microprocessor PID thermo-regulator assures precise temperature control with the tolerance not more than ±0.02°С throughout the whole operating range. It sets and monitors temperature, service parameters, performs control of the heater and cooler, troubles diagnostic and low liquid level cut-out. Transparent baths accommodates two glass capillary viscometers of various types which can be easily mounted on the top of the unit with a universal holder. A draining tap, installed in the bottom of the baths, makes its refilling very simple.
Features and benefits:
- Powerful compressor cooler allows the instrument to achieve as low temperatures as -40°С within only 1.5 hours
- Intelligent control system LOIP-ATC automatically adjusts PID-control parameters according to the fluid properties and eliminates influence of mains oscillations
- A high performance motorized stirrer ensures temperature uniformity throughout the baths
- In case of malfunction (e.g. due to low fluid level) auto-testing system stops the instrument, gives visual and acoustical alarm and displays the causes
- High precision temperature sensor Pt-100
- Accurate three-point calibration of temperature readings
- LED illuminating system makes the observation of viscometers very comfortable
