Technical data: External dimensions: 200 × 310 mm Height: 90 mm Rating: 1200 Watt Voltage: 230 Volt Weight: 2.6 kg Article Order No. High-performance heating plate 43 06 05400 Precision Hot Plates, Gestigkeit Hot plates PZ 44 bis 450°C Hot plates with microprocessor control of temperatures from room temperature up to 450°C. The electric heater has 3 power levels (825 – 1650 – 3300 W.) Each level can also be adapted by electronic power outputs in the range from 10 to 100% in order to prevent the temperature being overshot. Temperature levels 1 and 3 heat the plate over its full sur- face. Level 2 (1650 W) heats only the right-hand half of the plate, creating a temperature gradi- ent (40% of the set temperature) to the left-hand half. There is also a bushing to connect a contact thermometer and temperature cut-out. Design: Hot plate made of smoothly finished, solid cast iron GG 15 in low-distortion quality. Hous- ing parts made of stainless steel (material No. 1.4301), bottom section also enameled. Four adjustable feet ensure wobble-free standing. Sturdy construction able to take a maximum load of 150 kg. Ready to connect with 1.7 m cable. Technical data: External dimensions (W × H × D): 320 × 190 × 470 mm Plate size (W × D): 290 × 440 mm Weight: 23 kg Rating: 3300 W Temp. control range: +20 to 450°C Switching difference: ±1 K Article Order No. Hot plate PZ 44 for 230 V 43 06 00110 Hot plate PZ 44 for 2 × 400 V 43 06 00111 Cable with connector for temperature cut-out, timer, contact thermometer 43 06 00119 1 2 4 5 3 Precision Hot Plates, Gestigkeit DIGITAL ELECTRONIC hot plates are designed for continuous and equipped as standard with a built-in temperature limiter adjustable from 30 to 100°C or 50 to 300°C. Because of asymmetrical, quick-reaction, special long-term heating and thermal sensors, as well as output adaptation to the thermal requirements, extremely precise temperatures, with a very good uniform heat are obtained over the complete heating surface. Design: Upper plates are made of efficient heat-conducting aluminium alloy and have a smooth anodized finish. Temperature is regulated by means of a microprocessor temperature controller with digital actual value display. Operating temperatures are preset in 0.1°C divisions up to 99,9°C and in1°C divisions for temperatures over 100°C. All models are fitted with an electronic output regulator allowing the heating output to be adjusted to actual demand. All models are equipped with a bushing to connect either a contact ther- mometer or a time switch. Models PZ 60, HB 110 and HB 300 have screw-in sockets for five 12mm diameter sup- porting rods with a clearance of 125 mm to each other.
