Works calibrated 

ELE Clamped Boss Load Rings are available in the range 

1 kN to 50 kN. 

The available capacities and performance of ELE 

load rings satisfy the requirements for accurate load 

measurement for a wide range of testing applications. 

The repeatability and accuracy of all clamped boss rings 

comply with the requirements of NIS 0415 Accreditation 

for the Calibration of Force Measuring Rings and Load 

Cells used in Soil Testing. 

The repeatability of all load rings is within 0.2% of 

indicated load and accuracy is ±1% of indicated 

load over the upper 80% of the working range, at the 

calibration loads. 

All clamped boss load rings are calibrated in kN and 

supplied with a calibration chart. 

Complete with a detachable nipple, all rings are supplied 

in a protective foam moulding.

Rapid Drying 

Hotplate 

A hotplate offers an alternative method of drying 

materials in bulk. Even heat distribution is not as good 

as an enclosed chamber, however sensible use of the 

hotplate will often enable test requirements to be met 

satisfactorily.

Large Capacity Drying Oven 

These ovens are designed for drying large quantities of 

soils and aggregate samples and maintain temperature 

in accordance with BS1377. 

Constructed from mild steel with a coated exterior and 

an aluminium coated steel chamber, the ovens are fitted 

with a thermostatic control and feature fan-circulation for 

even temperature distribution throughout the interior. A 

safety overheat thermostat is fitted as standard and the 

units are supplied with the temperature indicator pre-set 

to 105 – 110°C.

Test Sieves 

Particle Size Analysis 

Particle Size Analysis is probably performed in most, if 

not all, laboratories engaged in testing materials for civil 

engineering applications. The range of sieves offered 

include ISO, EN, BS and ASTM sieves. 

Woven wire test sieves are manufactured from stainless 

steel mesh. Perforated plate test sieves are manufactured 

from tinned steel plate. All test sieves, unless otherwise 

indicated, are supplied with full-depth frames.

80 Laboratory Equipment - Sieve Shakers 

Sieve Shaker 

Hand sieving of a large number of samples can often be 

tedious and sometimes lead to inaccuracy of results. The 

following machine provides a wide choice of options for 

the busy laboratory. 

ELE Sieve Shaker 

EN 932-5 

The ELE sieve shaker is powered by an electromagnetic 

drive that has no rotating parts to wear making it 

maintenance free and extremely quiet in operation. 

The unit features a triple Vertical-Lateral-Rotary vibrating 

action that moves the sample over the sieve producing 

faster more efficient sieving, while the rapid vertical 

movements also help keep the apertures from blinding. 

The shaker is ideal for laboratory or on site use. It 

is robust, compact and sufficiently lightweight to be 

portable. The separate digital microprocessor controlled 

console unit incorporates a keypad for setting the sieving 

program and is isolated from any effects of vibration 

from the shaker. 

As standard the shaker includes, timer 0-999 minutes, 

adjustable vibration intensity and adjustable intermittent 

or continuous operation. 

EL80-0200/01 ELE Sieve Shaker 

The unit accepts up to ten 200 mm or 8 inch, full height, 

diameter sieves and lid and receiver, or up to six 300 mm 

or 12 inch diameter sieves and lid and receiver. 


EL80-0200/01 ELE Sieve Shaker complete as specified. 

Dimensions (l x w x h) 380 x 440 x 1085 mm. 

Weight 65 kg. For 220 – 240 V AC, 50 Hz 1ph.
