1 INTRODUCTION

Thank you for purchasing the Oakton T-100IR Portable Turbidimeter (hereafter referred to
as the instrument). The instrument is designed using the principle of scattering and
conforms to the ISO 7027, (DIN EN 27027) methods for measuring the turbidity of aqueous
solutions and is suitable for use in laboratories or on site.

The instrument provides accurate results with the simple calibration and testing, giving you
unparalleled ease of use and accuracy.
⚫ The instrument has intelligent functions such as automatic calibration, operation

navigation, parameter Setup, real-time clock display, calibration date check, automatic
power off, low voltage indication, and a replaceable tungsten light source.

⚫ Large TFT color screen with blue background for measurement mode, green

background for calibration mode, and operation guides for easy calibration and
measurement, optional English & Spanish menu for convenient operation.

⚫ 500 sets of data storage with USB data output to PC.
⚫ Normal and continuous two kinds of measurement mode. Continuous measurement

mode with the option to select the number of continuous measurements, automatically
generating average, maximum and minimum measured values in a data storage
interface, suitable for sample solutions with rapid settling and continuous measurement
changes.

⚫ It meets IP67 water-resistant grade requirements and is suitable for field use.

⚫ Product comes in a rugged carrying case, including calibration solutions, sample test

cuvettes, and more.
