摘要： A water quality measuring system includes a first introduction section for introducing rearing water as a sampling target, and a first adding section which adds an acid to the rearing water introduced by the first introduction section, and a nitrous acid sensor whose measurement target is nitrous acid and which measures the measurement target concentration of the rearing water to which the acid has been added by the first adding section. The water quality measuring system includes a second adding section which adds a base to the rearing water introduced by the first introduction section, and an ammonia sensor whose measurement target is ammonia and which measures the measurement target concentration of the rearing water to which the base has been added by the second adding section.

摘要： A particulate sensor (10) to be attached to a gas flow pipe EP through which a gas to be measured EG containing particulates S flows. The particulate sensor (10) includes a gas introduction discharge pipe (31); a discharge element (60) including a discharge electrode member (62) maintained at a discharge potential DV and which electrifies particulates contained in the gas under measurement, and a sealed portion (60C) located on a proximal end side GK of an element distal end portion and in which the discharge electrode member is disposed and insulated from the outer surface (60CS) thereof; a surrounding member (38, 39) maintained at a first potential SGND; and an electrically conductive glass seal (37) which establishes electrical communication between the surrounding member and the pipe (31), and is in close contact with the outer surface of the sealed portion of the discharge element to provide gastight sealing.

摘要： A particulate sensor (1) includes an ion source (15) and a reference potential member (45). The particulate sensor (1) detects particulates S contained in a gas under measurement EG by means of ions CP. The ion source (15) includes a ceramic structure (100) having a ceramic laminate (101) and a discharge electrode member (110). The discharge electrode member (110) has an inter-layer portion (112A, 111) embedded between the layers of the ceramic laminate (101) and an exposed portion (112B) extending from the inter-layer portion (112A, 111) to a position outside the ceramic laminate (101). The discharge electrode member (110) generates the gaseous discharge between the reference potential member (45) and the exposed portion (112B) including one or more needle-shaped distal end portions (1125) upon application of a constant DC discharge potential PV2.

摘要： A water quality measurement device (100) includes a flow channel (130), an ion sensor having a responsive film portion whose surface is disposed in the flow channel (130), a glass-electrode-type sensor having a glass electrode whose surface is disposed in the flow channel (130), a drive section (115), a first opening-closing section, and a second opening-closing section. When a storage condition is satisfied, the water quality measurement device (100) puts the first opening-closing section in a first closed state and puts the second opening-closing section in a second closed state, thereby producing a state in which the surface of the responsive film portion and the surface of the glass electrode are present in a common closed space (135) whereby the closed space (135) is put in a wet state without the surface of the responsive film portion being immersed in the liquid.

摘要： A particulate sensor includes: an inner metallic member which is maintained at a first potential and which has a gas introduction pipe into which a target gas is introduced; a tubular outer metallic member which surrounds the radially outer circumference of the inner metallic member and which is attached to a gas flow pipe to thereby be maintained at a ground potential; and an insulating spacer which is interposed between the inner metallic member and the outer metallic member so as to electrically insulate them from each other and which has a tubular gas contact portion which is exposed to the interior of the gas flow pipe and comes into contact with the gas under measurement. The insulating spacer has a heater for heating the gas contact portion. The heater includes a heat generation resistor embedded in the insulating spacer.

摘要： A particulate measurement system measures the amount of particulates when at least one or a plurality of three operating condition parameters selected from speed of the vehicle, rotational speed of the internal combustion engine and torque of the internal combustion engine fall within previously set respective ranges, and the particulate measurement system does not measure the amount of particulates or invalidates the result of measurement of the amount of particulates when the one or plurality of operating condition parameters do not fall within the previously set respective ranges.
