Product Overview
The HV-RW are samplers intended for outdoor use. These products sample suspended dust
in the open face, and provide quantitative analysis of dust concentration and composition.
High-accuracy flow rate control is provided by a differential pressure detection system, and
instantaneous and cumulative flow rate values are displayed digitally. Reductions in suction
flow rate due to increased dust collection are minimized thanks to a constant flow rate
function. This product can be used to collect airborne dust by attaching the through pipe.
Similarly, it can also be used to collect dioxins by attaching the shuttle tube (tube for
polyurethane foam attachment). It is capable of stable, high flow rate sampling, and so can be
used under a wide range of conditions as an airborne toxic substance sampler.
Features
Fold up design makes movement and storage convenient.
Capable of high accuracy flow rate control thanks to a differential pressure detection
system.
The instantaneous and cumulative flow rate can be operated with 20
°
C and 1 atmosphere
correction, 25
°
C and 1 atmosphere correction, 0
°
C and 1 atmosphere correction, or actual
flow rate.
Incorporates a constant flow rate function to minimize drops in the suction flow rate
accompanying increased suction pressure caused by sampling of dust, etc.
A backlit touch panel is adopted to enable even more convenient operation.
Two timer functions are provided for starting operations: a delay timer based on the time,
and a clock timer based on the calendar date. Two types of timer sampling for ending
operations are also available: a sampling timer based on the time, and a volume timer
based on cumulative flow rate. Manual operation without using the timers is also possible.
A brushless motor is adopted, minimizing dust generation and extending motor life.
Noise reduction implemented.
If a power outage occurs, the remaining sampling is continued automatically after the power
recovery.
The high volume through pipe and shuttle tube for polyurethane foam attachment are easy
to attach.
The polyurethane foam can be left in the shuttle tube for storage or conveyance, shielding it
from light and air (HV-RW for dioxins).
Absolutely no grease is used in the sampling line.
A sampling data recording function is provided. The past 5 sampling results can be checked
on the sampler. Data can also be retrieved by connecting a PC and entering a
communication command.
