The measurement of the bending strength of foundry sand is essential for quality control, efficiency improvement, and safety assurance in the casting process, playing a crucial role in the foundry industry. This device is used to produce (sinter) test specimens for the bending strength test of foundry sand. 【Features】 ■ The sintering temperature (up to 280°C) and sintering time can be set arbitrarily. ■ One sintering cycle is completed in a few minutes, and it can produce five pieces of samples simultaneously. Continuous sintering is also supported. ■ Equipped with various abnormal detection functions such as overheating, heater disconnection, and leakage current. ■ The sintering mold can be opened and closed with button operation, considering safety. ■ High-precision temperature adjustment is possible with PID control. *Please feel free to contact us for more details.

• Temperature and humidity measuring instruments

This device is used to produce test pieces for the cast sand thermal expansion meter (EOS-3). It can simultaneously create two test pieces in a single firing. 【Features】 ■ Firing temperature (up to 280°C) and firing time can be set arbitrarily. ■ Each firing is completed in a few minutes, allowing for continuous production. ■ Equipped with a high-precision temperature adjustment function using PID control. ■ The dimensions of the produced test pieces are 22mm × 50mm, compatible with EOS-3. *Please feel free to contact us for more details.

• Temperature and humidity measuring instruments

Phototoxicity testing of raw materials for pharmaceuticals and cosmetics has traditionally been conducted using animal experiments, often yielding unreliable results. As an alternative testing method, a light source device for photoreactivity testing of chemicals (ROS assay) is used, where reagents are exposed to simulated sunlight and reactive oxygen species are detected using a microplate reader. Our company manufactures and sells "ROS Assay Quartz Reaction Containers."

This device allows for the simultaneous measurement of the necessary performance evaluation parameters for thermoelectric conversion materials—"electrical resistivity," "Seebeck coefficient," and "thermal diffusivity"—under the same sample and environment (using a single apparatus) from near room temperature to high temperature. Electrical resistivity is measured with high precision using the DC four-probe method, the Seebeck coefficient is measured using the steady-state method, and thermal diffusivity is measured using the periodic heating method. This device was developed with the support of the Ministry of Economy, Trade and Industry's Strategic Base Technology Advancement Support Project, in collaboration with Nagoya University and the National Institute of Advanced Industrial Science and Technology. 【Features】 ■ Capable of measuring three physical properties: electrical resistivity, Seebeck coefficient, and thermal diffusivity with a single sample ■ Unifies the direction of thermal propagation and current for the three physical properties ■ Measurement is possible by simply contacting the probe to thin sheet samples with a thickness of less than 1mm ■ Supports a temperature range from near room temperature to 900°C under atmospheric, vacuum, and various gas atmospheres ■ Dedicated software allows for monitoring of measurement conditions and output of measurement results (in CSV format) *For more details, please refer to the catalog or feel free to contact us.

The "MODEL RZ2001i" is an evaluation device that automatically measures the thermoelectric power (Seebeck coefficient) and electrical conductivity of thermoelectric conversion materials in high-temperature atmospheres. In thermoelectric measurements, a temperature difference is generated across the sample to measure the thermoelectric power (steady direct current method), and a constant direct current is passed through the sample to measure the conductivity. Please make use of this system developed under the technical guidance of the National Institute of Advanced Industrial Science and Technology's Synergy Material Research Center. 【Features】 ■ Sample temperature can be variably measured (up to 1000°C, 170 steps) ■ Measurements can also be conducted in various atmospheric gases ■ Compatible with prismatic and cylindrical samples ■ Thermoelectric power and electrical conductivity can be measured simultaneously ■ Automatic measurement is possible by simply turning on the switch after setting the sample *For more details, please refer to the catalog or feel free to contact us.
