Simplifying heat flow
measurement

Introducing
November a new compact
2015
heat flow logger!
Available in

Affordable

Simultaneously measure up to
10 channels.

— Measurable parameters —

Heat flows

Featuring a small lightweight
design that’s readily portable.

Thermocouples

Voltage

Pulse

Also measure and record voltage
and pulse data.

User
Friendly

High
sensitivity

10mV f.s.

Ideal for evaluating insulation
performance and analyzing the causes
of temperature change

HEAT FLOW LOGGER
LR8432

*Heat flow sensors and thermocouples sold separately.

Visualize the underlying causes of temperature change.
Temperatures change due to specific reasons.
Heat flow measurement lets you pinpoint those reasons that have been difficult to identify until now.
Application

1

See whether automotive parts are releasing or absorbing heat

By identifying why temperature rises, you can design optimal insulation and heat dissipation characteristics.

Conventional approach to measurement : Thermocouples only

New approach that adds heat flow measurement : Thermocouples + heat flow sensors

When vehicle stops

Time

It’s clear that the temperature increases but not why,
making it difficult to develop thermal countermeasures.

While driving : Releasing heat
While stopped : Absorbing heat

While stopped

The temperatures of parts
in the engine compartment
are measured using
thermocouples.
0̊C

Application

When the vehicle stops, the graph changes
from positive to negative.
In short,

Positive side:
Releasing heat
Negative side:
Absorbing heat

0̊C

Evaluate the thermal performance
of building materials

Basic Specifications

(Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)

The performance of insulating materials can be
compared in an effective manner.

When vehicle stops

High heat flow:
Low insulating properties

Low heat flow:
High insulating properties
By comparing the magnitude of heat flows,
you can confidently choose building materials
with high insulating performance.

Number of channels

10 analog channels + 4 pulse channels
(Standard equipment; pulse ground common with instrument)

Maximum sampling speed

10 ms for all channels

Power supply

AC adapter (standard accessory), battery pack (optional), or
external power supply

Dimensions and weight

176 (W) × 101 (H) × 41 (D) mm, 550 g

External storage media

CF card, USB flash drive

Measurable parameters

Voltage, heat flow, thermocouple, pulse, RPM

Voltage measurement range

±10 mV to ±60 V (maximum resolution: 500 nV)

Numerical calculations

Up to four simultaneous calculations: Average value, peak
value, maximum value, minimum value, maximum value time,
minimum value time, integration

Waveform calculations

Perform basic operations between channels (+, -, ×, and ÷) and
display the results as calculation channel (W1 to W10) data (valid
during measurement only).Calculate data for the specified
channel from the simple average, moving average, integration,
or coefficient of heat transfer and display as calculation channel
(W1 to W10) data (valid during measurement only).

Measure curved surfaces!

Heat flow sensors
B ecause they can bend, these
flexible sensors broaden the range

Measure small parts alone

Now you can measure objects that were
impossible to isolate for measurement
before, for example the surfaces of small
par ts and narrow gaps resulting from
increasing miniaturization of technology.

By identif ying whether heat is
being released or absorbed, you
can implement optimal thermal
countermeasures.
