As a mechanical engineering company with more than 70 years of experience in the manufacture of environmental simulation systems, we at Köhler-VLM are experts in the field of corrosion testing. Our origins date back to 1951, when we developed the first Kesternich condensation water system in collaboration with Wilhelm Kesternich. With our many years of experience and outstanding expertise, we always offer you the best possible advice and are constantly striving to improve. Today, our diverse systems can be found in a wide range of quality assurance and development areas. We offer series devices...

JUMO controller (PID)Optimum temperature stability through precise control The function of the microprocessor controller (PID) The devices in the EC, LS, QS, HP, BIO, HT and VIS product lines are equipped with the JUMO PID controller. The PID control parameters allow fast heating rates without overshooting and guarantee precise temperature control of the samples (see diagram). Calibration: If the temperature shown on the display deviates from the value measured in the heating block over time, it can be adjusted by the user using the calibration function. All heating blocks have a 4 mm sensor...

Temperature control using the example of an EC-1V metal block thermostat The diagram shows the exceptional performance of the JUMO controller using the EC-1V thermostat as an example. The PID control parameters are set at the factory to achieve a practical compromise between a fast heating rate and low temperature overshoot. The heating tray reaches the set temperature of +100°C after just 17 minutes. The heating block is initially heated up at full power during the heating-up phase. In the equalization phase, the heating is reduced to such an extent that the heating block reaches the set target...

Quality guaranteefor reliable results in the laboratory Kohler-VLM metal block thermostats meet the highest demands in terms of: ✓ Precision of the temperature control ✓ Electrotechnical and mechanical processing We develop, produce and test the devices in accordance with the standards applicable to laboratory devices: High-quality components We adhere to our quality guidelines at all times and only use VDE-tested components from well-known manufacturers. The appliances are manufactured by our experienced specialists at our Geseke site and then individually adjusted and tested. High reliability...

Metal block thermostats 130°C/210°C for exchangeable heating blocks QS thermostats +130°C/+210°C are designed for a smaller number of samples and tight budgets. The compact devices are equipped with the highquality JUMO microprocessor PID controller. Its high precision as well as the timer, ramp and calibration function are the reason for its superior performance in this price range. In addition to thermostats with heating trays for exchangeable heating blocks with drilling depths of up to 65 mm, we also supply devices with permanently installed blocks according to your specifications. Heating...

LS thermostats are not "cheap heaters", but represent the low-cost alternative to BIO thermostats. In order to accommodate tight budgets, the mechanically very complex, solid aluminum heating tray has been dispensed with in favour of a mounted tray. Its base is also precision-milled to ensure good heat transfer to the heating blocks. Equipped with the JUMO controller (PID) and a wide range of heating blocks, the LS circulators are perfectly matched to the requirements of life science laboratories. HP thermostats +130°C/+210°C "High Performance" thermostats are equipped with a liquid-tight solid...
