KELLER will exhibit at the Hydrogen and Fuel Cell Expo! March 17-19, 2026 at Tokyo Big Sight, West Hall 2, W15-36.

The pressure sensor for hydrogen applications has finally arrived!

The 23SY-H2(Ei) series is characterized by a low embrittlement rate due to an increased nickel content in the stainless steel used. The gold-plated diaphragm minimizes hydrogen diffusion. Additionally, the pressure sensor is compensated across the entire temperature range, providing excellent long-term stability. The 23SY-Ei-H2 series is a reliable solution equipped with long life, high precision, and safety, meeting various hydrogen requirements. 【Features】 〇 Adoption of stainless steel with increased nickel content as a measure against hydrogen embrittlement 〇 Use of gold-plated diaphragm widely used in hydrogen applications to minimize hydrogen diffusion 〇 Achieves ±0.7% accuracy within -10 to 80°C 〇 Excellent long-term stability 〇 Welded structure without internal seals 〇 Available in intrinsically safe explosion-proof type (23SY-Ei-H2)

The digital pressure gauge for hydrogen applications has finally arrived! With logging function.

The high-precision digital pressure gauge LEO Record H2 is a digital pressure gauge that can record pressure and temperature over long periods. By increasing the nickel content in stainless steel, it ensures a low embrittlement rate and a long service life. Additionally, the gold-plated diaphragm minimizes the diffusion of H2. With the RS485 interface, the pressure gauge can be easily connected to a PC for settings and data retrieval. Its high accuracy and safety allow the LEO Record H2 to meet the requirements for measuring instruments in the hydrogen field. 【Features】 • Use of stainless steel with increased nickel content to counter hydrogen embrittlement • Gold-plated diaphragm to minimize hydrogen diffusion • Records pressure and temperature • High data security with non-volatile memory • Ultra-low power consumption / long battery life • Various pressure units selectable (bar, mbar, hPa, kPa, MPa, PSI, kg/cm2, etc.) • Zero point calibration via button • Recording function can be manually started and stopped • Various recording function settings available • Available in intrinsically safe explosion-proof type (LEO-Record-Ei-H2)

We would like to express our congratulations on the continued prosperity of your esteemed company. Our company will be exhibiting at the following trade show, where we will be showcasing a number of products, including our new product, the Packaging Container Air Leak Test (Pin Hole Inspection) Device | MSQ-2003 series. We sincerely apologize for the inconvenience during your busy schedule, but we would like to cordially invite you to attend this event. 【 Trade Show Name 】 【 Dates 】 【 Venue/Booth Number 】

We will showcase our new product "BLFF," a palletizing foam gripper that weighs only 1.9 kg and measures 350mm×250mm, ideal for bulk picking. We will also introduce various products that cater to different work applications, including durable suction cups and solutions for bag handling. Additionally, we are implementing energy-saving proposals by replacing ejectors to reduce compressed air consumption, which has become a challenge in many industries. If you have any issues with adhesion or transport, please feel free to consult with us at the venue. ■ Lightweight Foam Gripper for Collaborative Robots "CVGC Series" Despite weighing only 1.9 kg, this gripper has a theoretical lifting force of 100 kg, maximizing the payload capacity of collaborative robots. ■ Gripper for Films This gripper is designed to transport thin films gently, minimizing marks left on the surface. By utilizing 3D printing, we can accommodate highly flexible shape designs tailored to specific workpieces and applications. ■ Energy Saving Comparison Panel "Why does a single ejector consume less compressed air compared to a multi-stage ejector?" You can actually verify the differences in compressed air consumption through a comparative display using a flow meter and actual equipment.
