REED INSTRUMENTS R2450SD Thermocouple Thermometer, 2 Channels

REED Instruments R2450SD data logging thermometer is ideal for recording temperatures, up to 3092 degrees F, either manually or automatically at the desired sampling rate from 1 to 3600 seconds. This data logging thermometer comes with a beaded wire probe, a soft carrying case & batteries for use in medical, educational, R&D, pharmaceutical, food service and environmental monitoring applications.

Working Mechanism:

• Switch on or off the data logging thermometer by holding down the POWER button for 2 seconds.
• Connect up to four thermocouples out of thermocouple Types K, J, T, E, R or S to the T1 through T4 input jacks on the unit's top.
• Press & hold the TYPE button for scrolling through the thermocouple types & select the desired type on the LCD by releasing the button to confirm the selection. The LCD should display the selected channel's temperature values.
• In the RTD (Pt100 Ohm) measurement mode, connect up to two RTD probes (R2450SD-RTD) to the PT1 & PT2 RTD input jacks.
• Press & hold the TYPE button for scrolling through the temperature sensor types till the LCD shows the 'Pt' icon. Release the TYPE button for confirming the selection. The LCD should display the selected channel's temperature values.

Features:

• REED Instruments R2450SD data logging thermometer displays up to 4 separate temperature measurements in an easy-to-read backlit LCD using Type K, J, R, S, E & T thermocouples and RTD probes.
• It can manually record up to 99 readings and automatically store data in real-time using an SD memory card.
• This data logging thermometer can measure current temperature, temperature differential (T1-T2) and maximum & minimum temperature to quickly produce an Excel file without using any software.
• It has a data hold function to freeze the reading (on display) and a user-selectable temperature unit scale (degree C / degree F).
• This data logging thermometer has a low battery indicator & an auto shut off mechanism (after 10 minutes) for saving battery life.
• It uses 6 AA batteries or an AC adapter for powering the unit.
• This data logging thermometer is operated at temperatures ranging from 32 to 122 degrees F (0 to 50 degrees C) and humidity less than 85% RH.
