The Challenge: When Environmental Conditions Can’t Be Guessed

Whether you’re commissioning an HVAC system, assessing water damage, monitoring a cool room, or ensuring museum-grade climate control, accurate humidity and temperature measurement isn’t optional – it’s essential. Guesswork leads to mould growth, equipment failures, spoiled goods, and compliance headaches.

Australian conditions make this particularly challenging. From humidity spikes during wet seasons to the bone-dry air of inland summers, environmental monitoring requires instrumentation that handles extremes while delivering readings you can trust and document.

The real problem? Many basic humidity meters lack the precision, logging capability, or professional features needed for compliance documentation and thorough site assessments. You need measurements you can record, review, and present with confidence.

Introducing the REED R6040 Psychrometer/Thermo-Hygrometer

The REED R6040 addresses these challenges with a purpose-built solution combining psychrometric measurement capabilities with comprehensive data logging. This isn’t a basic humidity pen – it’s a professional instrument designed for technicians who need accurate, documented environmental data.

Measuring relative humidity from 0 to 99.9% RH with ±2% accuracy, the R6040 simultaneously monitors ambient temperature (-20°C to +70°C) and calculates dew point and wet bulb values automatically. The backlit LCD displays temperature and humidity readings together, giving you instant environmental assessment at a glance.

What sets the R6040 apart is its documentation capability. With internal memory storing up to 999 reading groups and user-selectable sampling intervals from 1 second to nearly an hour, you can create comprehensive environmental profiles for any assessment. Whether you’re monitoring a drying chamber over several days or conducting spot checks across a facility, the R6040 captures it all.

Key Capabilities That Matter in the Field

Precision You Can Rely On

The R6040 delivers ±0.3°C temperature accuracy and ±2% RH humidity accuracy – specifications that meet professional monitoring requirements. The 0.1 resolution on all measurements means you’re capturing meaningful changes, not just ballpark figures. For dew point calculations, the instrument provides ±0.8°C accuracy across an impressive -78.2°C to +70°C range.

Comprehensive Data Logging

Environmental conditions change. Single-point readings rarely tell the full story. The R6040’s 999-group memory with adjustable sampling rates lets you build complete environmental profiles. Set sampling from 1 second for rapid changes to 59 minutes 59 seconds for extended monitoring periods. Manual recording is also available for spot-check documentation.

Visual Alarm System

Set high and low thresholds for proactive monitoring. The R6040’s visual alarm system uses colour-coded indicators – red for high alerts, blue for low – making it immediately obvious when conditions drift outside acceptable ranges. Perfect for monitoring critical environments where you can’t afford to miss threshold breaches.

PC Connectivity and Analysis

Download logged data via USB-C to the included Windows software for detailed analysis. Generate charts, review trends, and produce reports that document environmental conditions throughout your assessment period. The software supports Windows 7 through Windows 11, ensuring compatibility with most site laptops and office systems.

Practical Design for Fieldwork

At just 102 grams and 155mm long, the R6040 fits comfortably in a shirt pocket or tool pouch. The belt clip keeps it accessible during site work, while the backlit display ensures readability in poorly lit spaces like ceiling voids, basements, and mechanical rooms. Auto shut-off preserves battery life, while the low battery indicator prevents unexpected power loss during critical measurements.

Data Logger
The Reed Portable Gun thermometer is capable of storing up to 20 data locations. During the recording the infrared temperature and temperature scale (°C or °F) are also stored. You can store values during the infrared reading. While holding the trigger, press the MODE button until LOG appears in the lower left corner of the display; a log location number will be shown. If no temperature has been recorded in the shown LOG location, 4 dashes will appear in the lower right corner. Aim the unit at the target area you want to record, and press the laser/backlight button. The recorded temperature will appear in the lower right corner. To select another log location, press the up and down keys.

Recalling Data
To recall stored data after the unit shuts off, press the MODE button until LOG appears in the lower left corner. A LOG location number will be shown below LOG, and the stored temperature for that location will be displayed. To move to another LOG location, press the UP and Down keys.

Measurement operations
Hold the meter by its handle grip and point it toward the surface . to be measured. Pull and hold the trigger to turn the meter on and begin testing. . The display will light if the battery is good. Replace the battery . if the display does not light. While measuring, the SCAN display icon will appear in the upper left corner of the LCD. Release the trigger and the HOLD icon will appear on the LCD . indicating that the reading is being held. The meter will automatically power off approximately 7 seconds after the trigger is released. Unless the unit is locked on.

How to obtain Emissivity?
In the EMS mode, press and hold the Laser/Backlight button until . the “EMS” icon on the left side of LCD blinking. At this time, “ 3 = –” . will appear at the upper side of the LCD; IR temperature value will be in the middle of LCD; and Type K temperature value is at the lower side of the LCD.Contact the Type K probe to the object surface and test the temperature of same point with IR measurement. After both values are stable, press UP or DOWN button for confirmation. Then, emissivity of the object will be shown at the upper side of the LCD. Press MODE button or trigger to enter normal measurement.
