Rapid hydrogen analyzer

Jr-hda-vRapid hydrogen analyzerIt can accurately and quickly measure hydrogen in aluminum and aluminum alloy melts.

Aluminum hydrogen analyzerWorking principle:

Adopting the "closed loop circulation method", in accordance with Sievert's law (Alscan and Telegas hydrogen meters are strictly adhered to)Formula definition: [H]=K A K T S 0 pH 2

KA - correction factor for aluminum alloy *, related to alloy composition, pure aluminum is 1.00

PH2- hydrogen partial pressure in a closed loop (atmospheric pressure)

KTS0- Saturation solubility of hydrogen in aluminum under different temperature conditions, with a saturation solubility of 0.92ml/100g for pure aluminum at 700 ℃

Note: The JR-HDA-V hydrogen analyzer strictly conforms to the above formula, and its KA, KT, and S0 parameters all meet the general definition.

JR-HDA-V and ALSCAN conducted comparative tests on the same flow channel samples using their respective probes, and the errors were within a reasonable range (5% or ± 0.01ml/100g). Our company has on-site video materials available for those in need.

The differences in main functional configurations between JR-HDA-V and ALSCAN:

Motherboard: JR-HDA-V has better integration and anti-interference ability than ALSCNA

Sensor accuracy: The thermal sensor and the thermal sensor have comparable accuracy over the full range

Upper computer software: capable of graphically reading measurement files from instruments, used for data analysis and management, as well as remote computer control of instruments

Display: JR-HDA-V graphical interface, superior to ALSCNA digital tube, convenient for on-site control of sampling probe operating conditions.

USB data management: JR-HDA-V can transfer measurement files to personal computers for data analysis and management anytime and anywhere

Automatic termination after measuring balance: Extend probe life while ensuring accurate data conditions

Power supply: JR-HDA-V is equipped with a 9.8Ah lithium battery and built-in charger, with a theoretical working time of over 7 hours

Humidity hydrogen content: equipped with a humidity meter to measure the environment (the instrument automatically calculates the hydrogen content of the aluminum melt in equilibrium with the environmental humidity)

Probe failure detection: warning prompt when the measurement curve does not conform to the defined measurement principle

Measurement balance detection: There is a warning prompt when the measurement curve does not conform to the defined measurement principle

Data storage: JR-HDA-V stores 500 sets of measurement data in file format, while ALSCNA stores over 100 sets

Probe: The service life of both hydrogen measuring probes is equivalent, and the measurement reproducibility of the same sample with different probes is good (within an acceptable range of error)

On site printing: Real time printing of measurement process and result data

Long cycle measurement: facilitates the adjustment of various process parameters of the degassing equipment during process research (JR-HDA-V long cycle measurement is 60 minutes)

Communication: Used for connecting with personal computers, remote control operations, and transferring measurement files to personal computers for data analysis and management after connection

Probe swing: used when necessary to accelerate the measurement speed of molten materials that are stationary or have a flow rate less than 5cm/s

Gas cylinder capacity: JR-HDA-V supports more data in one inflation, approximately 150 measurements, with the same inflation method for both

There is video evidence to support this: HDA-V has conducted on-site comparative testing videos with ALSCNA hydrogen meters in six companies. Leakage experiment video of external circulation probe (aluminum oxide hydrogen probe)

HDA-V hydrogen analyzer is equipped with HP-xxxxx series hydrogen probe, which can also be used for ALSCNAHydrogen analyzer, HP-xxxxx series hydrogen measuring probe is an internal circulation probe, and its service life is similar to ALSCAN hydrogen measuring probeThe probe is equivalent (see technical specifications in the table below) to the external circulation probe (used with the ELH hydrogen analyzer for oxidation)Compared with aluminum hydrogen probes, aluminum hydrogen probes have the following characteristics:

1. The internal circulation probe ensures no "leakage" and its measurement results are accurate and true. Existing external circulationThe probe generally has a problem of "leakage" (which cannot be overcome by existing technology), and its measurement results are low.

2. Due to their different working principles, the "attenuation failure" effect of the internal circulation probe is significantly better than that of the external circulation probeThe ring probe has a longer service life than existing external circulation probes.

3. The internal circulation probe is not affected by the melt flow rate or probe insertion angle, therefore the measurement accuracy is higher,More convenient operation.

4. The connection between the internal circulation probe sampling head (part in the aluminum melt) and the stainless steel capillary tube is integratedSeamless connection, capable of withstanding high temperatures (800 ℃), while existing external circulation probes are made of epoxy resinSealing (* can withstand up to 200 ℃). Therefore, in harsh on-site environments, the external circulation probe is capable ofEasy to leak and fail.

5. The external circulation probe is prone to splashing of molten material during the measurement process (in a blown state), causing safety hazards to both personnel and the instrument.
