The real strength of the 26800 is the ability of the user to custom program the device to perform virtually any task.
A user-friendly PC program allows easy formatting of the program parameters, display screens and recording functions. Programming is also possible using front panel controls when a PC is unavailable.

The 26800 has built-in memory for storage of large amounts of recorded data. More than 2 million data points may be stored. Data retrieval is simplified by the handy communication program provided.

The 26800 is supplied with a large selection of sensor inputs. Wind, temperature, precipitation, humidity and other sensors are easily connected through the back-panel terminals. Frequency, voltage, current-loop and serial inputs are provided. All values are completely scalable in the program

Many output options are available from the 26800. Terminals are available for calibrated voltage outputs and current outputs as well as serial outputs. Switched outputs provide alarm capability.

Compact configuration is easily panel mounted. Adjustable stand permits table top use as well.

The 26800 is compatible with a wide variety of sensors andaccessory devices. Terminals for all functions are readily-available on the back panel. Convenient, plug-in terminal blocks simplify wiring and service needs after installation.

Conventional wind inputs such as frequency and analos voltage signals are accommodated. Potentiometer excitation is provided for direction sensors.

Connections for temperature devices, including platinum RTDs and thermistors, are made through back panel terminals.

Up to 16 voltage inputs are available allowing connection of humidity sensors, barometers, pyranometers and other devices. Many scaling options are available.

4-20 mA current loop systems are no problem when long cable lengths or noisy industrial settings are present.

High resolution voltage outputs allow operation of chart recorders and other external devices.

Four low-level control outputs are provided to allow alarm actuation or relay control.

Both RS 232 and RS485 connections are available allowing easy communication with PCs and other devices.
