Introduction
Thank you for purchasing this Cole-Parmer product. To get the best performance from the
equipment, and for your own safety, please read these instructions carefully before use.
Before discarding the packaging check that all parts are present and correct.
This equipment is designed to operate under the following conditions:
❖ For indoor use only
❖ Use in a well ventilated area
❖ Ambient temperature range +5°C to +40°C (+41°F to +104°F)
❖ Altitude to 2000 m (6500 ft)
❖ Relative humidity not exceeding 80%
❖ Use with a minimum distance all round of 200 mm (8 in.) from walls or other items
If the equipment is not used in the manner described in this manual and with accessories other than
those recommended by the manufacturer, the protection provided may be impaired.
General Description
The temperature controller is the ideal instrument for the accurate temperature control of aqueous
and oil based samples in the laboratory. The temperature controller can be used in two different
modes: as a precise temperature controller from 20 to 200°C (68 to 392°F ) or as a digital
thermometer from -4 to 325°C (24.8 to 617°F). With digital setting and display of temperature, the
temperature controller is accurate to ±0.5°C (±1°F).
The temperature controller is compatible with the following Cole-Parmer hotplates and hotplate
stirrers:

Safety Advice
❖HIGH TEMPERATURES ARE DANGEROUS as they can cause serious burns to operators and
ignite combustible material. Users should be aware of the following safety advice:
❖USE CARE AND WEAR PROTECTIVE GLOVES TO PROTECT HANDS.
❖DO NOT use combustible substances near hot objects.
❖NEVER lift or carry the instrument until it has been switched off and allowed to cool for at least 30
minutes. The hot warning light will give guidance.
❖The unit should be carried using both hands with the fingers under the side edges.
❖NEVER move or carry the unit with containers on the top plate or while still connected to the power
supply.
❖There is a danger of liquid spillage if containers are over-filled and stirred at high speed. Always
build stirrer speed slowly and never stir more rapidly than necessary.
❖NEVER place a cold glass vessel onto a hotplate which is already hot.
❖NEVER use a retort rod longer than 600 mm (23.6 in.).
❖When a retort rod is installed with apparatus attached, or when swivelling support rods, take care
that there is sufficient weight on the plate to prevent the whole unit tipping over.
❖When using a retort stand, in order to provide the unit with adequate ventilation the base of the
retort stand must NOT exceed 19.5 mm (0.75 in.) in height and 125 mm (5 in.) in width.
Installation Instructions
The Temperature Controller is designed for use with either a metal top or ceramic top hotplate
(compatible models listed under General Description heading).
Place the hotplate on a firm, level surface. Open the jaws of the retort clamp on the rear of the
temperature controller by turning the clamp dial counter-clockwise. The clamp can be used with retort
rods from 9.5 to 13 mm (0.37 to 0.5 in.) diameter. Slide the temperature controller on to the retort rod
and tighten by turning the clamp dial clockwise.
NOTE: DO NOT OVER-TIGHTEN
Connect the temperature controller plug to the DIN probe socket at the rear of the hotplate
(see Figures 1 and 4).
Connect the probe plug to the probe socket at the rear of the controller (Figures 2 and 4). To ensure
the best connection, tighten the locking collar on the plug by turning clockwise.
Connect the power supply lead to the IEC socket at the rear of the hotplate and switch the unit on.
To switch on the temperature controller, turn the heat control dial on the hotplate clockwise (Figure 3).
NOTE: The controller power is supplied by the hotplate
The temperature controller and hotplate are now ready for use. Correct communication between the
temperature controller and the hotplate is indicated by the illuminated amber temperature controller
indicator on the front panel of the hotplate.
NOTE: The hotplate and controller will perform an automatic self-test at power up, before
the current temperature of the probe is displayed. The factory default set temperature is
20°C (68°F).
