Safety Information
This section gives instructions for promoting safe and proper handling of the Particle
Analyzer.
Laser Safety
The Model TCH Pro 20x handheld Particle Analyzer is a Class I laser-based instrument.
•During normal operation, you will not be exposed to laser radiation.
•WARNING: Class IV visible or invisible laser inside. Exposure to this light causes
blindness.
•DO NOT remove any cover or disassemble the device.
Important - Take these precautions
•DO NOT remove any parts from the particle analyzer unless you are specifically told to do
so in this manual.
•DO NOT remove the housing or covers. There are no user serviceable components inside
the housing. All repair and maintenance needs should be done by a qualified technician.
•Take precautions not to get any particles over 50 μm inside the unit. Failure due to
foreign objects found in the unit are not covered by the Warranty.
•Precautions for power use:
•AC Adaptor. The AC adapter accommodates voltage of AC 100~240V and frequency of
50/60 Hz.
•Batteries: 2 units of Li-ion, 3.7V, size 18650.

Chapter 1: Product Overview
INTRODUCING TCH PRO MODELS
The Handheld Particle Analyzer TCH Pro is a lightweight, handheld particle counter with a
3.5” Color LCD display, a touchscreen and a single button. It is simple to use and maintain.
It operates on battery or AC power. This model series has a 0.1 CFM with internal flow
meter (1% FS) and active flow control counts particle sizes of 0.2μm (50%) to 10μm full and
continuous particle size spectrum by turning the concept of channels obsolete. Over 1,000
data sets can be stored in removable SD card and downloaded for analysis and reporting
using the utility included with the device.

Chapter 2: Unpacking
Carefully unpack Teilch Handheld Particle Analyzer from its case and verify that all the items
shown in the photos below and listed in the following tables are present. It is recommended
to unpack the particle counter within a cleanroom-type environment. Doing so will minimize
the counter’s exposure to dirt and moisture.

Chapter 3: Theory of Operation
A clean, contamination-free work environment is critical to maximize yields as certain
particles are likely to cause defects, irregularities, inaccuracies and even failures. Analyzing
particle contaminants is an important step in having control over operating environments
and reducing particle deposition in critical components.
Isolating, characterizing and understanding the types of particles found in products or
processes can usually yield a likely source for the particles. Once the source is known then
elimination of the particulate contamination becomes substantially easier.
II. PARTICLE DETECTION
PARTICLE COUNTING PRINCIPLE
A particle counter is an instrument that detects and counts particles. A particle counter
works on the principle of either light scattering, light blocking, or condensation for detecting
and measuring particle size or size distribution.
When a particle is illuminated by a light beam, light is reemitted (if light scattering is used) or
absorbed (obstruction). The scattered or absorbed light (depending on method used) is
detected by a photo detector, measured, and the particle is counted and tabulated into
standardized counting bins. If direct imaging is used, light illuminates particles from the back

within a cell while a high definition, high magnification camera records passing particles.
Recorded video is then analyzed by computer software to measure particle attributes.
Notes:
•The light blocking optical particle counter method is typically useful for detecting
and sizing particles greater than 1 micrometer in size. This type of technique allows high
resolution and reliable measurement.
•The light scattering method is capable of detecting smaller sizing particles. Typical
detection sensitivity of the light scattering method ranges between 0.1µm to 25µm.
Scattered light is significantly smaller for small particle sizes. A 0.2µm particle emits
1*10-10 of the intensity emitted by a 10µm particle.
•The condensation method is used to detect particles over 5nm, but it cannot
differentiate among different particle sizes.
