PSL (Poulten Selfe &
Lee) specialises in the viscosity
measurement of petroleum products (new & used) and the dilute
solution viscosity measurement of polymers and pulp. PSL maintains
a primary viscosity scale and its calibration activities are accredited
by UKAS, demonstrating that the company's calibration laboratory
fully complies with ISO 17025.

- Designed specifically to meet
the requirements of standard test methods, ISO/DIS
3104, 3105, ASTM D445-IP71, ASTM D2515, ASTM D446,
BS188, DIN 51562, 52007.
- The bath accommodates up to seven manual viscometer
tubes and two thermometers
- Supplied with levelling feet, stainless steel lid
and covers
- 40-litre capacity
- A built in cooling coil can be connected to the
optional, TLC-1 cooling circulator. This allows the
bath to operate in the range 15 to 40°C
under normal ambient conditions of 20 to 25°C

- BS718: 1991 - sub-series
150, M50, S50 and M100
For each series the hydrometers are graduated to indicate
density at 20oC. Instruments from 0.6 to 1.0 are adjusted
for liquids of LOW surface tension, whereas those
from 1.0 to 1.5 are adjusted for liquids of MEDIUM
surface tension.
