AD1020 is a professional bench meter for pH, ORP (Oxidation Reduction Potential), ISE and temperature measurements. Relative mV readings are also provided.

Main features include:

• Up to 5-point calibration with 7 memorized buffers (pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01 & 12.45) and two custom buffers
• Calibration time-out alarm
• pH calibration using buffers with 0.001 resolution
• pH reading with manual or automatic temperature compensation
• Log-on-demand (up to 50 samples) and automatic logging (up to 1000 samples)
• Two selectable alarm limits
• User selectable logging interval mode
• Connection to an external serial printer with the following specifications:
• at least 16 characters / line
• baud rate 9600
• 9-pin RS232 input
• Large easy-to-read LCD showing pH or ISE, mV and temperature readings simultaneously, together with graphic symbols
• HOLD feature to freeze the stable reading on the LCD
• GLP feature to view last calibration data for pH, ISE and relative mV
• PC interface 

Supplied complete with

AD1020 is supplied complete with AD1131B refillable pH electrode with glass body, BNC connector and 1 m cable, AD7662 stainless steel temperature probe with 1 m cable, pH 4.01 & pH 7.01 calibration buffers (20 ml sachet each), electrode holder, 12 Vdc power adapter, and user manual.

AD8000 is a microprocessor-based pH, ORP, conductivity, TDS and temperature bench meter. Relative mV feature is also provided. The autoranging feature of the Conductivity and TDS ranges automatically sets the instrument to the scale with the highest resolution.

pH measurements are compensated for temperature effect automatically (ATC) using AD7662 temperature probe, while the EC readings can be compensated automatically (ATC) using the conductivity probe with built-in temperature sensor or manually (MTC). It is also possible to disable the temperature compensation and measure the actual conductivity.

The temperature coefficient is user selectable. The pH calibration can be performed at 1, 2 or 3 points with five memorized buffers (pH 4.01, 6.86, 7.01, 9.18, 10.01). In addition, AD8000 is provided with calibration timeout alarm, GLP feature to view last calibration data and automatic HOLD feature to freeze the first stable reading on the LCD.
