Introduction to the Unit
Overview
The M100+ is a process turbidimeter that allows for the laboratory
measurement of the turbidity of sample water. The white light M100+
has been designed to meet the design criteria specified by the US EPA
180.1 on turbidity measurement. The infrared M100+ was designed
to meet the criteria specified in ISO 7027 and DIN 27027 for the
measurement of the turbidity of a sample. Both models have long life
lamps.
The M100+ instruments are equipped with a USB slot in order to
download logged data and calibration information. The USB slot is also
used to update operating software.
The M100+ is equipped with a color touch screen for easy and efficient
operation.

§
The specifications found in EPA method 180.1 are essentially the same as the specifications set out
in method 2130B of the Standard Methods of the Examination of Water and Wastewater 22nd Edition
and the specifications set out in ASTM Standard Method D1889-94. The M100+ meets or exceeds
the specifications set forth in these methods.
†
Instrumental accuracy measured under controlled laboratory conditions at 25°C (77°F).
‡
Both the accuracy and repeatability specifications for the M100+ are valid only for measurement
of static (non-flowing) samples.

Unpacking and Inspection of the Instrument
Remove all items from packing carton and carefully inspect to ensure
that no visible damage has occurred during shipment and that all items
listed below have been received. If the items received do not match
the order, please contact your local distributer or the HF scientific
Customer Service department.
• M100+ Laboratory Turbidimeter
• Accessory Kit for M100+ (2 empty sample cuvettes with caps)
• Full Range Calibration Kit High Range A, High Range B,
1000 NTU, 10 NTU & 0.02 NTU
• Quick Start Guide
• Flash Drive - Contains full owner’s and user’s manual
• Wall Mount Power Supply with Ferrite
A ferrite is included with the power supply. This should be
looped twice through the cord near the side that connects to
the instrument to eliminate EMI interference.
NOTICE
Site Selection
The follow should be taken into consideration when selection a site for
the M100+ instrument.
• Must be in a suitable, dry location with adequate ventilation.
• Should not be located where chemicals, such as chlorine, are
located.
• Must be operated and stored between 1 and 40°C.
• Should be used on a stable table top.
• Table top location should be less than 90 cm (3 feet) from a
power source.
Power Requirements
The M100+ requires 12VDC for proper operation. The provided power
supply is rated at 1A.
The instrument is supplied with a wall mount power supply intended
for oepration with 100-240 VAC, 47-63 Hz power source.
Before
installing, verify that the line voltage falls within these
specifications.
The wall mount power supply connects to the instrument’s rear panel.
An optional Euro wall mount power supply is available.
Setup
Before using your M100+, you will need to familiarize yourself with the
instrument’s operating modes and functions and perform some setup,
configuration and calibration.
The M100+ allows for the measurement of the turbidity of water. The
turbidity of the water is usually reported in Nephelometric Turbidity
Units (NTU) but may be reported in Formazin Nephelometric Units
(FNU). This is user selectable.
Readings up to 4400 are possible but readings above 4000 are outside
of the rated specifications. Readings above 4400 NTU will cause the
display to flash, indicating an over-range condition.
During normal operation the instrument will be at the HOME screen.
This is the screen where measurements can be viewed.
Please note, some features depicted in this manual may change with
future firmware updates.
