Product Overview
The Kaye HTR-420 is the most advanced high temperature calibrator specifically designed to
address the capacity and flexibility needs for thermal validation. The HTR-420 offers a broad
temperature range from 30°C to 420°C with temperature stability of ±0.010°C and uniformity of
±0.1°C. Performance of calibration and calibration verification can either be performed
automatically via Remote mode or manual through Standard mode.
The Kaye HTR-420 has been designed to interface directly
with all Kaye products (Validator AVS, Validator 2000, IRTD,
ValProbe, and RF ValProbe). The firmware is backward
compatible with all version of Kaye software without need for
software upgrades. This functionality allows the unit to be
utilized for fully automatic calibrations/verifications of
thermocouples, ValProbes or RF ValProbes utilizing your
existing IRTD and applicable Kaye software.
The Kaye HTR-420 also has the flexibility to calibrate other
process or validation sensors in Standalone mode through the
intuitive 7” touchscreen, and a variety of optional inserts.
To maximum accuracy of the control and measurement
during calibration, the HTR-420 includes an external Control
Reference Probe. This probe is used for feedback to the
calibrator controller.
The calibrator is portable, rugged and can be used in a variety
of environments from 0°C to 50°C and humidity ≤80% (non-
condensing).

1.2 Dry-Block Function
The HTR-420 comes standard with a dry block insert containing sixteen (16) wells for thermocouples
as well as two (2) wells for IRTD, and one (1) well for the Control Reference Probe. Each of the
sixteen (16) thermocouple wells is included with a sleeve which can accommodate upwards of three
(3) thermocouples. The sleeves are optimized to handle 22AWG thermocouples, which are similar
others currently utilized in existing Kaye dry block models.
Kaye also offers additional dry block inserts for calibrating specialty processes or validation probes.
These inserts are easily interchangeable utilizing the supplied insert tool.

1.3 Calibration Modes
The HTR-420 was designed to offer flexibility and ease of use. To accommodate these needs
Kaye implemented two main modes or menu’s Remote Control mode and Standalone mode.
Remote Control mode is intended for
Automatic Calibration utilizing Kaye
Validator equipment (Validator 2000,
Validator AVS, ValProbe and RF
ValProbe). In this mode, control of
the HTR-420 and the touchscreen
interface is automatically driven by
the appropriate Kaye software. In the
Kaye software, the user configures
the set points, the stability criteria,
and deviation criteria. The user
simply starts the calibration from the
Kaye software and the control of the
calibration is automated. No
additional interaction with the
touchscreen is required. The HTR-
420 when powered on automatically
boots into the Remote Control
screen.
The Standalonemode is intended
again to offer flexibility by allowing
fully manual configuration of the
HTR-420 to define all different kinds
of parameters from different types of
sensors, ramp and soaks setups
/profiles to address other calibration
needs. For Standalone mode, refer
to Chapter 6 Standalone Manual
Mode and Chapter 7 Starting
Standalone Manual Calibration for
details the options and screen flows
to manually configure the HTR-420.
