3 ABOUT THIS PRODUCT
3.1 Overview
The personal mini pump NX-300 is a lightweight, portable air sampling pump equipped with functionality
for measuring accumulated flow rates. The flow rate for this pump is 10 mL/min to 300 mL/min, which in
the air sampling pump lineup from Nextteq is a particularly low flow rate range.
It is equipped with a pressure loss correction function and a constant flow rate function. The pump is
controlled so as to maintain the set flow rate even if you are using sampling tubes with different pressure
loss values, or the pressure loss changes during sampling. As a result, this can be used as an air sampling
pump for toxic substances in work environments, indoor environments, and ambient environments.
3.2 Features
A pressure loss correction function is built in, which suppresses intake flow rate fluctuations if
sampling tubes with different pressure loss values are used with the same set flow rate.
A constant flow rate function is built in, which suppresses intake flow rate
fluctuations if a sampling material is used with a pressure loss that changes due to sampling.
An organic EL graphics display has been adopted as the indicator, so you can
check the flow rate information even in a dark location.
The product can run for approx. 10 hours on two alkaline batteries (100 mL/min, unloaded
conditions).
The USB terminal can be connected to a mobile battery* with an output of at least 5 V DC and
500 mA or to an AC adapter for use as an external power supply.
* The product might not operate properly depending on the mobile battery specifications.
NX-300 Constant Flow Range of
10-30 mL/min is a perfect pump for
TWA Nextteq tubes and other low
flow applications.
NX-300 withstands high back pressure –
perfect for use with sorbent tubes.
At 190g (with batteries), 6.70 oz,
the NX-300 is the lightest low flow,
constant flow sampling pump in the
market!
With 10 hours of operation on two
alkaline batteries (100mL/min,
unloaded conditions), provides a full
days’ use with no downtime.
The small size allows one to fit the
NX-300 in a pocket!
W 63 mm – 2.5 in
D 29 mm – 1.1 in
H 115 mm – 4.5 in
Organic Electroluminescent (organic
EL) graphics display allows use in
dark locations.
An operating temperature and hu-
midity range of 0-40˚C (32-104˚F)
and 10-90% RH, makes the NX-300
ideal for almost any application.
