These values are to be considered only as approximate values. The sensor resistance largely de-
pends on the temperature and humidity conditions during the time of exposure to harmful substances.
Avoid simultaneous condensation. Tolerated error of measurement: ± 2 % r.h. The maximum work
place threshold limit value is the one that can be regarded as harmless for humans.
•Vapors of oil and fat are dangerous for the sensor because they may condensate at the sensor and
thus prevent its function (insulating layer). For similar reasons it is not possible to measure smoke
gases.

2. Chamber description
The alternating climate chamber MKF / MKFT is a specially developed precision cooling/warming cabinet
for the domain of industrial material testing and environment simulation, with an unrivalled capacity, which
far exceeds the capabilities of normal test cabinets, providing the ideal facilities for solving all the prob-
lems which occur during material as well as ageing and stress tests.
The chambers are equipped with a multifunctional microprocessor display controller with 2-channel tech-
nology for temperature and humidity plus a digital display accurate to one-tenth of a degree resp. 0.1%
r.H. With its comprehensive program control functions, the display program controller MB2 permits the
high precision performance of temperature and humidity cycles with rapid heating up and cooling down
phases.
With its microprocessor controlled humidifying and dehumidifying system the chamber is a high-precision
climatic test chamber. It covers the regular test specifications for temperature and climates corresponding
to DIN und IEC standards. Furthermore, it permits simulating exactly and over long periods constant con-
ditions for other applications such as sample conditioning for material testing of paper, textiles, plastics,
building materials, etc.
The patented APT.line™ preheating chamber and air conduction technology guarantees excellent spatial
temperature and humidity values for the total working area. The chamber provides a powerful refrigerat-
ing system with rapid cooling-down speeds. In addition, the chamber provides almost unlimited possibili-
ties for adaptation to individual customer requirements based upon extensive programming options.
A resistance humidifying system humidifies the air. For this purpose, use deionized (demineralized) wa-
ter. The option BINDER Pure Aqua Service permits using the chamber with any degree of water hard-
ness.
The high-quality housing insulation guarantees both a low noise mode of operation and a consistently low
housing temperature. The inner chamber, the pre-heating chamber and the interior side of the doors are
all made of stainless steel V2A (German material no. 1.4301, US equivalent AISI 304). When operating
the chamber at temperatures above 150 °C / 302°F, the impact of the oxygen in the air may cause discol-
oration of the metallic surfaces (yellowish-brown or blue) by natural oxidation processes. These colora-
tions are harmless and will in no way impair the function or quality of the chamber. The housing is RAL
7035 powder-coated. All corners and edges are completely coated.
The efficient program controller is equipped with a multitude of operating functions, in addition to recorder
and alarm functions. Programming of test cycles is easily accomplished via the modern touchscreen con-
troller MB2 and is also possible directly with a computer via Intranet in connection with the APT-COM™ 4
Multi Management Software (option, chap. 21.1). The chamber comes equipped with an Ethernet serial
interface for computer communication. In addition, the BINDER APT-COM™ 4 Multi Management Soft-
ware (option) permits networking up to 100 chambers and connecting them to a PC for controlling and
programming, as well as recording and representing temperature and humidity data. For further options,
see chap. 25.6.
The chambers are equipped with four castors. Both front castors can be easily locked via the attached
brakes.
