Temperature Measurement With an Immediate Printed Record

The Anritsu Meter AP-400 Series is useful when a temperature reading must be documented at the point of measurement. Instead of writing values down by hand or transferring data to a computer, the operator can print the measured temperature and time directly from the handheld instrument.

The built-in thermal printer supports individual readings, automatic printing at selected intervals and numbered measurement records. Up to 100 readings can also be stored in memory and printed together later. This makes the AP-400 and AP-450 suitable for inspections, maintenance rounds, production checks and verification work where a paper record is useful.

Choose the connector and thermocouple type carefully

The AP-400 uses an ASP probe connector, while the AP-450 uses an ANP connector. Each instrument is manufactured for one thermocouple type, which cannot be changed from the keypad. Confirm the probe connector and thermocouple type before ordering.

AP-400 or AP-450?

Feature	AP-400	AP-450
Input channels	1	1
Input connector	ASP	ANP
Thermocouple options	Type E or K	Type E, K, J, T or R
Can the thermocouple type be switched?	No; order the required type	No; order the required type
Typical reason to choose it	Existing ASP probes or straightforward E/K temperature measurement	ANP probe compatibility or a requirement for J, T or R thermocouples
Legacy replacement	Application dependent	Successor for AP-800, AP-800K, AP-800E, AP-850K and AP-850E applications, subject to probe and connector review

Printing and Memory Functions

Function	How it works	Where it helps
Manual print	Press the print key to record the measured value with the measurement time	Individual inspection points and spot checks
Interval print	Automatically prints readings at the selected time interval	Short-duration process tests and temperature trends
Number print	Prints sequential numbering together with the measured values	Documenting a series of products, locations or test points
Memory print	Stores up to 100 readings and prints them as a batch	Recording measurements where immediate printing is inconvenient

Thermocouple Measurement Ranges

Thermocouple type	1 °C resolution range	Availability
Type E	−200 to +800 °C	AP-400 or AP-450
Type K	−200 to +1370 °C	AP-400 or AP-450
Type J	−200 to +1100 °C	AP-450
Type T	−200 to +400 °C	AP-450
Type R	0 to +1760 °C	AP-450

For E, K, J and T versions, the instrument provides 0.1 °C resolution within the specified intermediate range and automatically changes to 1 °C resolution outside that range. Type R operates at 1 °C resolution.

Measurement Accuracy

Thermocouple and resolution	Temperature region	Instrument accuracy
E, K, J or T at 0.1 °C resolution	0 °C and above	±(0.05% of reading + 0.2 °C)
E, K, J or T at 0.1 °C resolution	Below 0 °C	±0.5 °C
E, K, J or T at 1 °C resolution	0 °C and above	±(0.1% of reading + 1 °C)
E, K, J or T at 1 °C resolution	Below 0 °C	±(0.5% of reading + 1 °C)
Type R at 1 °C resolution	Full specified range	±(0.1% of reading + 3 °C)

Reference-junction compensation accuracy is ±0.2 °C at 25 °C ±10 °C. Probe accuracy, installation technique, surface contact and the response of the selected sensor must also be considered when estimating total measurement uncertainty.

Popular Anritsu Temperature Probes

The probe should be selected for the measurement target, not just the expected temperature. These commonly specified Anritsu probe families cover surface, internal, food and moving-surface measurements.

Probe series	Best suited to	Why choose it
Anritsu A Series	Stationary surfaces	General-purpose contact probe for routine surface-temperature measurements
Anritsu AX Series	Stationary surfaces where probe alignment may vary	Contact-support head helps the sensor remain closely seated against the target
Anritsu CS Series	Small components and restricted surface areas	Compact sensor head reaches measurement points that are too small for a conventional surface probe
Anritsu MG Series	Stationary ferromagnetic surfaces	Built-in magnet holds the probe in position for convenient hands-free monitoring
Anritsu BS Series	Liquids and semi-solid materials	General internal-temperature probe with a configurable insertion sheath
Anritsu BC Series	Food, liquids and semi-solid products	Washable food probe designed for hygienic centre-temperature measurement
Anritsu ST / STN Series	Flat stationary surfaces and installed measurements	Thin, flexible tape-shaped sensor can be fixed directly to the measurement surface
Anritsu U Series	Moving or rotating surfaces	Contact-pressure control helps reduce measurement error caused by friction while improving sensor durability
Anritsu UX Series	Moving or rotating surfaces where alignment may vary	Flexible contact-support head follows the target more closely and remains stable during measurement
Anritsu SH Series	Small moving or rotating surfaces	Compact contact head is intended for smaller targets where a standard moving-surface probe is unsuitable

Check the probe code before ordering

The AP-400 requires an ASP connector, while the AP-450 requires an ANP connector. The probe thermocouple type must also match the fixed input type of the instrument. Seacom can check the complete probe code, temperature limits, head construction and cable specification for your application.

Typical Applications
