Hotplates

Adjustable hotplates for general laboratory use. A metal grille protects the user against inadvertent contact with the hot surface and also prevents the vessel from falling off the hotplate.

For continuous operation. Electric hotplates with thermostatic temperature control and separate power controller for performance adjustment to the heating requirements. Anodised aluminium alloy hotplate. Excellent uniform temperature distribution over entire heating surface. Asbestos free. Stainless steel housing, with painted central section. Height-adjustable feet. Mains cable approximately 1.7m. With earthed plug for 230V supplies up to 3300W. A 400V 3-phase model is also available.

Maximum temperature 300 °C. Digital setting and control of plate temperature with 1 °C resolution and cast aluminium/silicon alloy top plate. The 300 x 300 mm top plate model has a retort rod mounting at the rear of the housing. With BioCote, silver-based, antimicrobial protection. For 230V 50/60 Hz single phase supplies.

For monitoring and control of electronic heating equipment, such as heating mantles, heating baths, heating mats, water baths, oil baths etc. Fitted with state of the art control electronics.

Multiple hotplate systems, 360 W, with individually adjustable heating controls and indidicator lights. Maximum surface temperature 400 °C.

An alternating current safety controller for variable and no-loss control of hotplates, heating tapes, soldering irons, light bulbs, infrared radiators etc.
Potentiometer scale adjustment and electronic triac switch monitoring. Controller switches irreversibly to dipole in the event of triac switch malfunction and visual and audible alarms operate immediately. This ensures optimum safety.

Automatic, precise regulation of temperatures between 20 and 450°C. Digital presetting and temperature display. Three power levels (825W, 1650W and 3300W) can be set and an additional electronic power controller (adjustable 10% to 100 %) is provided. At 825W and 3300 W settings the entire plate surface is heated. At 1650W setting only the right hand side of the plate is heated. As a result of heat conduction, the temperature from the right hand side to the left edge of the plate varies by approx. 40%. Built-in relay allows direct connection of electronic contact thermometers. With solid, flat, low-distortion, cast GG15 alloy. Switching differential ±1K.

For continuous operation. Provide extremely accurate, uniform temperatures, even in plate corners and on edges. Polished anodised aluminium heating surface. Microprocessor-controlled temperature controller with temperature setting up to 99.9 in 0.1°C steps, over 99.9 in 1°C steps. Actual temperature displayed continuously. With separate power controller for performance adjustment to the heating requirements from 10 to 100%. Built-in relay allows direct connection of electronic contact thermometers. Adjustable temperature monitor from 50 to 300°C (with PZ 28-1, 30 to 110°C) to prevent excess temperatures.
