Congratulations on your purchase of the Relative Humidity and Temperature Datalogger. This datalogger measures and stores up to 16,000 relative humidity and 16,000 temperature readings over 0 to 100%RH and -40 to +70°C (-40 to +158°F) measurement ranges. The user can easily configure the logging rate, high/low alarm and start-mode, and download the stored data by plugging the module into a PC's USB port and running the supplied PC software. Relative Humidity, Temperature and Dew Point data can then be graphed, printed and exported to other applications. GPP (grains per pound) data can be viewed using the optional RHT10-SW software. The data logger is supplied with a long-life lithium battery, which can typically allow logging for one year. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.

The product is a non-isolated power module with a 12V input bus voltage from Texas Instruments, which provides step-down power conversion to a wide range of output voltages with a maximum output current of 10A. The module is suitable for space conscious digital systems that incorporate multiple processors.

The RHT10 is a humidity and temperature USB datalogger with a data storage capacity of 32000 readings. The included software can calculate dew point and grains per pound (grams per kilogram).

RH520A is a user-friendly humidity + temperature chart recorder that records up to 49,000 data points and can be transferred to a PC via RS-232 serial port for further data analysis.

Extech RH490-NIST Precision Hygro-Thermometer is a professional tool for HVAC and water damage restoration contractors. It features a fast response time, simultaneous display of humidity or GPP (g/kg) and temperature, dew point or wet bulb temperature, and data hold and min/max functions.

BFS481 is a NPN Silicon RF Transistor for low-noise, high-gain broadband amplifier at collector currents from 0.5 mA to 12 mA.

This document describes the usage and characteristics of Extech Relative Humidity Calibration Standards. The calibration standards are made using Sodium Chloride (NaCl) and Magnesium Chloride (MgCl) to provide reference values of 75% and 33% relative humidity, respectively. The standards should be used at room temperature and provide relative humidity reference values at different temperatures.

BFS480 is an NPN silicon RF transistor designed for low noise, low-power amplifiers in mobile communication systems such as pagers and cordless telephones. It operates at collector currents ranging from 0.2 mA to 8 mA, with a transition frequency (fT) of 7 GHz and a gain (F) of 1.5 dB at 900 MHz. The package contains two internally isolated transistors.

BFS466L6 is a dual NPN Silicon RF transistor, suitable for low voltage/low current applications. It is ideal for VCO modules and low noise amplifiers.

BFS460L6 is a dual NPN silicon RF transistor with a high fT of 22 GHz, suitable for low voltage/low current applications, ideal for VCO modules and low noise amplifiers, a low noise figure of 1.1 dB at 1.8 GHz, the world's smallest SMD 6-pin leadless package, excellent ESD performance, and two integrated transistors (TR1, TR2: die as BFR460L3)

BFS380L6 is an NPN silicon RF transistor with high current capability and low noise figure, suitable for wide dynamic range applications. The transistor operates at low voltage and is ideal for low phase noise oscillators up to 3.5 GHz.
