Data Loggers & Data Logging Meters

A data logger records measurements over time so you can download and review them later. This page lists the standalone data loggers we sell (REED temperature/humidity and AC voltage/current loggers), the data logging meters that measure and record in one handheld instrument, and the Crystal nVision reference pressure recorder.

Standalone data loggers

• REED R6020 Temperature & Humidity USB Data Logger: stores up to 16,000 temperature and 16,000 humidity readings, −40 to 158°F (−40 to 70°C) and 0 to 100% RH. It plugs straight into a USB port to download (no cables), has a sampling rate from 2 seconds to 24 hours, an LED alarm for set max/min values, and a wall mount bracket for long-term monitoring.
• REED R6030 Temperature & Humidity Datalogger: the same 32k-reading memory and ranges, with a dual LCD that shows current temperature, humidity, min/max and date/time. It downloads through the included USB cable and software and has a wall mount bracket with a security lock.
• REED R5003 AC Voltage/Current Data Logger: a dual input TRMS datalogger that records up to 256,000 AC voltage and current measurements (10 to 600V AC, 10 to 200A AC), with a sample rate from 1 second to 24 hours. Two AC current clamp sensors and two voltage sensors are included. CAT. III 600V.

Data logging meters

These meters measure and log in the same instrument.

• Temperature: REED R2450SD Data Logging Thermometer, which displays up to 4 measurements at once from type K, J, R, S, E and T thermocouples or RTD probes, with optional SD card memory expandable to 16GB.
• Humidity, heat stress and environment: REED R6050SD Data Logging Thermo-Hygrometer (relative humidity, ambient temperature, dew point and wet bulb), REED R6250SD Data Logging Heat Stress Meter (indoor/outdoor WBGT, black globe, wet bulb) and REED R4700SD Data Logging Environmental Meter (air velocity, temperature, humidity, light and contact temperature).
• Airflow and air quality: REED R4000SD (vane) and REED R4500SD (hot wire) data logging thermo-anemometers, and the REED R9910SD Data Logging Air Quality Meter for O2, CO2, CO, temperature and humidity.
• Sound and light: REED R8070SD and REED R8080 data logging sound level meters, the REED R8075 Data Logging Sound Meter with 16GB internal memory, and the REED R8100SD Data Logging Light Meter.
• Water quality: REED R3000SD data logging pH/ORP meter and REED R3100SD data logging conductivity/TDS/salinity meter.
• Vibration and force: REED R7000SD Data Logging Vibration Meter, and the REED SD-6020 and REED SD-6100 data logging force gauges, which record tension and compression in peak hold or normal mode.
• Pressure: the Crystal nVision Reference Pressure Recorder logs gauge and absolute pressure to 15,000 psi / 1,000 bar, stores up to 500,000 data points and samples at 10 readings per second from two modules.

Choosing a data logger

• Standalone logger or data logging meter: a standalone datalogger such as the R6020 or R6030 is left in place for long-term monitoring; a data logging meter is a handheld instrument that also records.
• Sampling rate and memory: the R6020 and R6030 sample from 2 seconds to 24 hours and hold 16,000 temperature plus 16,000 humidity readings; the R5003 samples from 1 second to 24 hours and holds 256,000 measurements.
• Software: the R6020, R6030 and R5003 include PC software compatible with Windows 7, 8, 10 and 11.

Frequently asked questions

Which data logger records temperature and humidity?

The REED R6020 USB data logger and the REED R6030 datalogger both record temperature (−40 to 158°F / −40 to 70°C) and humidity (0 to 100% RH), storing 16,000 readings of each. The R6030 adds an LCD display.

How do I download data from a REED data logger?

The R6020 plugs directly into a computer's USB port. The R6030 and R5003 connect with the included USB cable. All three include software for Windows 7, 8, 10 and 11.

Which data logger records AC voltage and current?

The REED R5003 dual input TRMS datalogger records two voltage or current measurements, or one of each, up to 256,000 measurements in total.

What is the difference between a data logger and a data logging meter?

A data logger is built mainly to record unattended over time. A data logging meter, such as the R2450SD thermometer or R8070SD sound level meter, is a handheld measuring instrument that can also log its readings.

Can a data logger ship with an accredited calibration certificate?

ISO/IEC 17025 accredited calibration is available on eligible instruments; ask at quote. The Crystal nVision ships with an ISO 17025 / A2LA accredited calibration certificate.
