Autovisc - Flow CUp timer

This instrument is specially designed for automatie flow time determinations. Its built-in optical sensor detects the start/ break of the liquid flow and counts the elapsed time, thus eliminating human error.

The integral water jacket enables accurate temperature control when connected to an extern al water circulating bath (optional). Suitable for all ASTM/BS/ISO 055.8 mm or DIN 058.0 mm cups.

Supplied with a separate cup stand for easy filling.

Features

• Sturdy construction
• LCD display of efflux time in sec., resolution 0.1 sec. DAccuracy: 0.05 %, repeatability: 0.5 %
• Power Supply:
• Portable operation: 2 x 9V batteries operated
• Mains Operation: 220V, 50Hz / 110V, 60Hz
• Standard package: Instrument, cup stand, spirit level, closing plate.

TemperatureNiscosity Calculator

These useful devices allow viscosity corrections to be calculated when tests are not carried out at the specified temperature. The device comprises of two discs one mounted on top of the other. The upper disc is rotated to the temperature specified and the corresponding viscosity value at other temperatures is simply read off.

Höppler Viscometer

An accurate and versatile instrument, suitable for absolute viscosity measurement of various transparent fluids such as lacquers, resins, oils, foods, cosmetics, chemieals

etc. as weil as gas products. The test method consists of timing the travel of a ball in a tube filled with the product sampie. The integrated water jacket, when connected

to external circulating bath (optional, see p.15), allows temperature contral from -20° to +120°C for high accuracy determinations.

Features & Performance

• Range: 0.5 to 100.000 cP/mPa.s
• Excellent visibility for accurate measurements
• Reproducibility: < 0.5 %
• Standard package: Viscometer, set of 6 balls for fluids, thermometer _1° to +26°C (other ranges optional), cleaning tool, calibration sheet.
