Features and Benefits
So you need multiple channels, battery power,
outstanding accuracy, and the ability to read many different
sensor types—but you don’t need all the power of a 1 ppm
Super-Thermometer. We have the answer for you.
Hart’s 1529 Chub-E4 Thermometer gives you four channels,
three major sensor types, lab-quality accuracy, and a ton of
great features, all at a price you’ll love.

Inputs
The Chub-E4 has four inputs for reading four different
sensors simultaneously, and we’ll configure those inputs in
any of three different ways according to your preference.
Choose four channels of thermocouple inputs, four channels
of PRT/thermistor inputs, or two channels of each. With this
thermometer, reading thermocouples, PRTs, and thermistors
accurately from the same device is no problem.
100-ohm, 25-ohm, or 10-ohm PRTs and RTDs are read using
ITS-90, IEC-751 (DIN), or Callendar-Van Dusen conversion
methods. Typical accuracies include ±0.004°C at –100°C and
±0.009°C at 100°C. Thermistor readings are converted using
the Steinhart-Hart polynomial or standard YSI-400 curve and
are as accurate as ±0.0025°C at 25°C with resolution of
0.0001°.
Thermocouple inputs read all the common thermocouple
types, including B, E, J, K, N, R, S, T, and Au-Pt, and
allow you to choose between internal and external reference
junction compensation. Typical accuracy for a type J
thermocouple at 600°C is ±0.35°C using internal reference
junction compensation and not including the thermocouple.
(Support for C and U type thermocouples is available.

PRTs and thermistors connect easily to the 1529 using
Hart’s patented mini DWF connectors, which accept bare wire,
spade lug, or mini banana plug terminations. Thermocouples
connect using standard or miniature terminations.
Measurements are taken each second and can be taken
simultaneously or sequentially. A special high-speed mode
allows measurements on one channel to be taken at the rate
of 10 per second.
Display
If you think three sensor types and four inputs sounds
versatile, wait until you see the display panel on the
Chub-E4. Displaying measurements in °C, °F, K, ohms, or
millivolts and choosing temperature resolution from 0.01 to
0.0001 are just the beginning.
You can also select any eight items from our long list of
displayable data fields to view on-screen. Choose
statistical functions such as averages, standard deviations,
and spreads; choose probe information such as probe type and
serial number; choose T1–T2 functions using inputs from any
two channels; or choose utility functions such as the date,
time, and battery power level. You can even save up to 10
screen configurations for easy recall.
The push of a single front-panel button also brings up a
simple menu system to easily guide you through all the
internal setup and memory options of the 1529. Probe
coefficients, sample intervals, communication settings,
password settings, and a host of other functions are all
easily accessible. |
