The YEK 306 oxygen bomb calorimeter uses automatic isoperibol measurement to determine the calorific value of coal, coke, fuel oil and biomass.

Automatic analysis and touchscreen control

An integrated colour touchscreen controls the instrument without an external computer. Water filling and draining are automatic. The catalog lists an approximate test time of 15 minutes; sample preparation and the selected method affect the overall workflow time.

Measurement and calibration

The specified temperature resolution is 0.0001 K and heat capacity stability is ≤ 0.20%. These describe different properties and should not be treated as calorific-value measurement accuracy. Calibration uses benzoic acid to verify heat capacity.

Laboratory conditions and quotation

The ambient operating range is +10–30 °C and the power supply is 220 V ±10%, 50 Hz. Include sample type, daily analysis count, reporting needs and required accessories in your enquiry. Installation, training, service and delivery scope are defined in the written quotation.

The YEK-MA100 halogen moisture analyzer has a 100 g weighing capacity, a 40–199 °C temperature range and a 5-inch colour touchscreen LCD.

Weighing and halogen heating

The weighing precision is 0.001 g. A halogen lamp heats the sample, combining weighing and drying in one instrument for moisture analysis. Select the temperature and method to suit the sample composition.

Touchscreen and automatic stop

Analysis is controlled through the 5-inch colour touchscreen LCD. An automatic stop mode is available. Analysis time depends on sample quantity, drying behaviour and the selected method.

Application and quotation preparation

Share your sample type, current reference method, target analysis frequency and reporting needs. Clarify weighing and temperature checks, accessories, data transfer, installation and service scope in the quotation.

The YEK-MF series 7 L ash muffle furnace provides PID temperature control for ashing and heat treatment, with model-dependent maxima of 1100–1600 °C.
