1. PRESENTATION

TK2000 and TK2002 Digital Thermometers operate with K-type thermoelectric probes (Nickel-Chrome / Nickel-Aluminium) and offer measurement ranges of -50°C to +1000°C

You can choose from a wide range of specialised probes, extension cables and a handle to tailor temperature measurements to your requirements (see §5 - Probes).

2. PROBE / THERMOMETER CONNECTION

The thermometers have either one (TK2000) or two (TK2002) female connectors. Each probe is fitted with a male connector with 2 flat locating pins (polarised plug). The pins are made of compensated material different to that of the K-type thermocouple, but give the same e.m.f. in the usage temperature range.

Made of thermosetting plastic, the connectors can tolerate temperatures up to +200°C continuously.

Probe male plug 8.2 mm 21 mm 16.5 mm 24 mm Femal socket in the thermometer

3. START-UP

These thermometers function with K-type thermocouple probes only.

■ Connect the probe(s) to the thermometer in T1 or T1 and T2.
■ Press ON and release (if the "battery low" symbol in the bottom left of the screen is displayed continuously, change the battery).
■ Put the probe in contact with the temperature measuring environment (ensure compliance with probe specifications).
■ Wait a few seconds (see probe response time).
- Read the measurement value when the reading has stabilised.

The TK2002 gives the value for thermocouple T1. LED "T1" goes off and LED "T2" comes on when the measurement switch button is pressed. Temperature on T2 is displayed and if there is no T2 thermocouple, the unit displays 1000 with the number 1 flashing.

LED "T2" goes off and LED "T2-T1" comes on when the measurement switch button is pressed again. The T2-T1 temperature difference is displayed and if there is no T2 thermocouple, the unit displays 1000 with the number 1 flashing.

To measure two temperatures of over 200^ C with a difference of less than 200^ C, the T1-T2 reading is given to a tenth of a degree.

■ Press the ON/OFF button when the measurement is complete.

It does not switch off automatically.

4. CHARACTERISTICS

Plug-in probe with a specific measurement range. E.g. with the SK7 air probe, the thermometer-probe measuring ranges -50°C to +250°C.

4.1 MEASURING RANGE

From -50^ to +1000^ in two measurement ranges: -50^ to +199.9^ and +200^ to +1000^ .

-50°C to +199.9°C with a resolution of 0.1°C.
■ +200°C to +1000°C with a resolution of 1°C.

NB: The range changes automatically at +200°C when the temperature is rising and at below 180°C when the temperature is falling.

4.2 DISPLAY

■ 2000-counts liquid crystal display (13.5mm).
■ Automatic reading of the "-" sign.
■ Display to a tenth of a degree : -50^ to +199.9^ .
If the range 1000^ C > 2000 counts is exceeded : when the couple is disconnected or off, the figure 1000 is displayed with the number 1 flashing.

4.3 THERMOMETER ACCURACY (in the 25°C reference range\*\*)

■ From -50.0°C to 0.0°C : + linearity +/-1°C*.

* See reading correction curves below.

** Outside the 25°C reference range, account must be taken of the error from cold junction compensation.

4.4 WARNING

■ The measurement points must be at the same electrical potential (TK 2002).

5. PROBES AND EXTENSIONS

5.1 REMINDERS

NB : For all the probes below, the actual thermocouple is located at the end of the probe and attached to the sheath (thermocouple at earth ground).

■ Probe response time : the response time for a thermocouple subject to a temperature scale represents the time at the end of which the e.m.f. reaches total variation. For a thermocouple in a high heat capacity environment, with good thermal conductivity and good heat exchange, the response time will be short (intrinsic response time).

On the other hand, if the environment is thermally unfavourable (e.g. still air), the actual response time may be 100 times or more that of the thermocouple. The values specified below were established in clearly defined conditions, i.e.

■ For surface, flexible and auto-grip probes by contact on a polished stainless steel plate coated with silicone grease.
■ The air probe in disturbed air (1m/s).
■ Other probes, by immersion in disturbed water at 90^ C (disturbance speed : 0,3 to 0,5 m/s).
■ The temperature ranges for each type of probe are given for use in a chemically neutral environment.

Using these probes in a corrosive environment can significantly reduce their life cycle or restrict the recommended operating range depending on the case.
