Extech’s RH200W Multi-Channel Wireless Hygro-Thermometer displays indoor temperature and humidity levels. You can connect up to eight wireless transmitters to remotely measure temperature and humidity levels up to 30 m (98 ft) away. The LCD displays icons that indicate indoor comfort levels as well as trending arrows that show the increase, decrease, or constant readings. It also records min/max measurements for the duration of each measurement session. Ideal for multi-room environmental monitoring for restaurants, manufacturing facilities, offices, homes, greenhouses, and storage/archive buildings.
The RH300 is a compact meter that is ideal for field applications. Simultaneously displays relative humidity (10% to 90% RH), air temperature and dew point or wet bulb. Calculates T1-T2 differential (air temperature minus external probe temperature) using optional probe (TP890), and T2 minus dew point. Built-in protective sensor cap. Other features include Data Hold, Auto Power Off, and MAX/MIN reading. Complete with 2 AAA batteries.
The RH350 displays humidity, dew point, wet bulb, temperature and temperature differential. The triple backlit LCD can be changed to display humidity, temperature, dew point or humidity, temperature and wet bulb or humidity, temperature and Type K thermometer. Can also display the temperature difference between Type K T1 and T2 or air temperature and Type K or Type K and dew point. Advanced features include built-in memory and recall of up to 99 data points, Min/MAX/Average readings from the captured data, data hold and selectable auto power off. Includes 2 Type K temperature probes, and four AAA batteries.
Measure humidity and temperature simultaneously with the RH390 Precision Psychrometer from Extech. A dual-illuminated readout can be alternated to display wet bulb and humidity, or dew point and humidity, or temperature and humidity. This handheld device registers temperatures from -22 degrees to 199 degrees F (-30 degrees to 100 degrees C) and measures the full spectrum of relative humidity with ±2% accuracy between 20 and 90% RH. Complete with carrying case and 9V battery.
This Humidity/ Temperature Datalogger records data on an SD card in Excel format for easy transfer to a PC for analysis. It features a Dual LCD that simultaneously displays Relative Humidity and Temperature, and a selectable data sampling rate of 5, 10, 30, 60, 120, 300, and 600 seconds. Each stored reading includes a date and time stamp. 10 to 95% Relative Humidity and 32 to 122°F (0 to 50°C) Temperature ranges. Complete with 6 AAA batteries, SD memory card, Universal AC Adaptor, and mounting bracket.
The SDL350 records data on an SD card in Excel format. Air Velocity/Air Flow meter with telescoping probe designed to fit into HVAC ducts and other small openings. Telescoping probe extends up to 7.05ft (215cm) maximum length with cable. Adjustable data sampling rate. Stores 99 readings manually and 20M readings via 2G SD card. Type K/J Thermocouple input for high temperature measurements. Large (9999 count) LCD displays Air Velocity or Air Flow and Temperature simultaneously. Record/Recall MIN, MAX, Data Hold and Auto power off. Complete with 6 x AA batteries, SD card, telescoping probe with cable, and hard carrying case.
