1.0 Overview
The MicroTPI/TPW allows for the measurement of turbidity in the field. The MicroTPI
was designed to meet the design criteria specified in ISO 7027 and DIN 27027 for the
measurement of the turbidity of a sample. The MicroTPW was designed to meet the
criteria specified in USEPA 180.1 on turbidity measurement.
1.1 Unpacking and Inspection of the Instrument and Accessories
The table below indicates items included in the turbidimeter shipment.
Item Quantity
Field Portable Turbidimeter with 4 AAA batteries installed 1
Instruction Card 1
Instruction Manual 1
Instrument Carrying Case 1
Calibration Set (0.02, 10.0 , 1000 NTU Standards) 1
Empty Cuvettes 2
Lens Cloth 1
Remove the instrument from the packing carton. Carefully inspect all items to ensure that
no visible damage has occurred during shipment. If the items received do not match the
order, please immediately contact the local distributor or the HF scientific, inc. Customer
Service department.
Warning: Extra care should be taken when unpacking, opening, and handling the
calibration standards and sample cuvettes in the Accessory Kit; surface
scratches or finger smudges on the cuvette surface may cause measurement
errors. Handle these items by the cap of the cuvette only.
Note: The instrument is shipped with the batteries installed.

Figure 1 is a depiction of the top of the instrument. The three main components of the
instrument are the sample well, the display, and the touch pad. The following sections
will describe the functionality of the display and the touch pad. The proper use of the
instrument and the sample well will be discussed in later sections.
Figure 1: Top view of the instrument (MicroTPW shown).
1.2 The Display
All of the items that can appear on the display are shown in Figure 2. The display is used
for reporting the turbidity levels and to provide user guidance in the calibration routine.
In addition, the display also has other icons that are used to indicate when the instrument
is in calibration mode & to indicate error conditions and battery warnings.

1.3 The Touch Pad
The touch pad has five buttons: ON/OFF, CAL, ↵, t, and u. The ON/OFF button is
used to turn the instrument on and off. The CAL button is used to enter or exit
calibration. The ↵button, when pressed and held can be used to index the current
sample, when the button is released it starts a reading or calibration. The tand u
buttons are used to change the calibration points.
