  • Page 10: Product Overview・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・・9

    4. Product Overview Most environmental and industrial measuring instruments for measuring gas concentration use calibration gas to calibrate the scale and perform measurements. Therefore, reliable calibration gases are naturally required to obtain reliable measurement values. Calibration gases are also required for the measurement of odours by olfaction, research on gas analysis methods, tests on the effects of gases on animals and plants, and tests on the effects of specific gases on various materials.

    6. Installation and set up Warning ① Since the calibration gas is flammable and toxic, place the Permeater in a local exhaust ventilation system or in a place with sufficient room ventilation. Poisoning or fire may occur. ② Provide a sink near this instrument. If you come in contact with toxic substances or if they get into your eyes, rinse them off immediately.

    Note: ① Dilution gases should be supplied at pressures between 0.15 and 0.6MPa. Exceeding 0.6MPa may cause damage this instrument. ② Use nitrogen or air for the dilution gas. If other gases are used, the flow rate may be abnormal or internal corrosion may occur.

  • Page 15: Connection Of The Dilution Gas・・・・・・・・・・・・・・・・・・・・・・・・・・・・・14

    6.2 Connection of the dilution gas For the dilution gas, use nitrogen or air in a high-pressure gas container, or purified air compressed by an oilless compressor. The dilution gas should be regulated to 0.15 to 0.6 MPa with an external regulator and supplied to the DILUTION GAS (dilution gas inlet) of the Permeater.
  • Page 16 Connect the inlet of the dust filter (with a 200cm tube) to the outlet of the pressure regulator. The hose to be connected to the regulator is φ6 (outer diameter) × φ4 (inner diameter). Use a fitting that fits this size. Replace the dust filter when it is blocked.
  • Page 17 ①Tighten the female nut on the short end of the tube to the male thread of the DILUTION GAS (dilution gas inlet) until it can be turned fully by hand. ②Use a 14mm spanner or the like to tighten the nut about 1/4 more.

    After adjustment, push in and lock the lock ring. Note: When the regulator in PD-1C is pressurized to a pressure greater than 0.4 Mpa, the safety valve works to release the dilution gas into the main unit case. During the release of the dilution gas, a leakage sound of dilution gas is heard.
  • Page 20 ③ Tighten the nut to hold the FEP tube. ④Check that the FEP tube does not come out easily by pulling gently. ⑤ When removing the FEP tube and connecting it again to CALIBRATION GAS (calibration gas outlet), cut approximately 10mm of the tube end and re-attach it. When discharging the calibration gas, remove the toxic substances by a pressure-free method before discharging them outdoors.

  • Page 21: Connecting The Earth And Power Cord・・・・・・・・・・・・・・・・・・・・・・・・・・20

    Warning  Position the instrument and connect tubes so that the CALIBRATION GAS (calibration gas outlet) is away from the breathing zone when use.  If only one CALIBRATION GAS outlet is used, close the other outlet. If it is left open, calibration gas will come out.

    6.6 Filling water into the constant temperature water bath ① Check the water level sensor before filling the water bath. Press the POWER button to turn on the PD-1C, and STATUS lights up in red. (If the power does not turn on, check the leakage breaker on the rear panel.) ②After about 10 seconds, the buzzer sounds and the touch screen displays the start screen.
  • Page 23 ⑤Check the WATER DRAIN (temperature water tank drain port) is closed. ⑥ Open WATER INLET (water filling port of the constant temperature water bath) and insert a funnel. ⑦ Make sure the inlet you are pouring water is WATER INLET. Watch the WATER gauge and pour water between levels H and L.
  • Page 24 Note:  If water is added during operation, the temperature may drop and cause a "Heating/Cooling error". If this happens, turn the power OFF, and restart the main unit.  When pouring water, reconfirm that the inlet is the WATER INLET. Pouring water into the TUBE HOLDER may cause it to malfunction.

When using the PD-1C, using the Manual mode will display only the temperature and flow rate on the main screen, making it ideal for measuring the diffusion rate Dr value.

After this time has elapsed, prepare the calibration gas. 4) Procedures after use After use, open the lid of the TUBE HOLDER with dilution gas flowing, and remove the tube holding cage.

During storage, pay attention to the color of the absorbent (green gel) in the storage container and replace the green gel as necessary if the absorption capacity decreases.

When disposing of the adsorbent material, dispose it as industrial waste or incinerate it. Some may emit hazardous gas by incineration. In such cases, use a chemical incinerator which has flue gas treatment equipment.

Please read this operation manual carefully and fully understand the contents therein before using this unit. We also recommend keeping this manual on hand while you use this unit.
  • Page 92 The diffusion rates listed in Tables 1 and 2 at the end of this document are the values actually measured by Gastec. For higher accuracy or for substances not listed in the table, it is recommended that actual measurements are carried out under the actual conditions of use. When using D-tube, the dilution gas flow rate should be in the range of 0.2 to 8.0 L/min.
  • Page 93 IM973100E1 The calculation for the use of a D-10 type D-tube is as follows To prepare C=5.0 ppm when using PD-1B series, set the water bath temperature to 30 °C, use D-10 type D-tube, and set the dilution gas flow rate F to 2.0 L/min. When using PD-1C, set the dilution gas flow rate F to 1.94 L/min.
